Abstract
Abstract An electrical connecting member, one surface of which is connected to a connecting section of a first electrical circuit member and another surface of which is connected to a connecting section of a second electrical circuit member. The electrical connecting member includes a holding member formed of an electrically insulative member. The holding member has a plurality of recess holes. The connecting member also includes a plurality of electrically conductive members provided in the electrically insulative member, insulated from each other. One end of the electrically conductive members is exposed on one surface of the holding member to be connected to the connecting section of the first electrical circuit member. Another end of the electrically conductive members is exposed on another surface of the holding member to be connected to the connecting section of the second electrical circuit member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
182 words
A method of manufacturing an electrical connecting member having a holding member formed of an electrically insulative materials and a plurality of electrically conductive members provided in a mutually insulated state in the holding member, one end of each of the electrically conductive members being exposed on one surface of the holding member and the other end of each of the electrically conductive members being exposed on the other surface of the holding member, said method comprising the steps of: providing photosensitive resin as the holding member on a base body; exposing the photosensitive resin to light by the use of a mask provided with light intercepting portions, light transmitting portions and light attenuating portions; developing the exposed photosensitive resin to thereby form apertures in which portions of the base body are exposed in the photosensitive resin and concave holes; removing the portions of the base body exposed in the apertures by etching to thereby form recesses; filling the apertures and the recesses with a material for the electrically conductive members and leaving the concave holes empty; and removing the base body.
Claim 2
Independent Claim
182 words
A method of manufacturing an electrical connecting member having a holding member formed of an electrically insulative materials and a plurality of electrically conductive members provided in a mutually insulated state in the holding member, one end of each of the electrically conductive members being exposed on one surface of the holding member and the other end of each of the electrically conductive members being exposed on the other surface of the holding member, said method comprising the steps of: providing photosensitive resin as the holding member on a base body; exposing the photosensitive resin to light by the use of a mask provided with light intercepting portions, light transmitting portions and light attenuating portions; developing the exposed photosensitive resin to thereby form apertures in which portions of the base body are exposed in the photosensitive resin and concave holes; removing the portions of the base body exposed in the apertures by etching to thereby form recesses; filling the apertures and the recesses with a material for the electrically conductive members and leaving the concave holes empty; and removing the base body.
Claim 3
Dependent Claim
27 words
A method according to claim 1, further comprising the step of disposing the electrically conductive members in a staggered fashion on the surface of the holding member.
Claim 4
Dependent Claim
26 words
A method according to claim 1, further comprising the step of forming a wiring pattern on one or each of the surfaces of the holding member.
Claim 5
Dependent Claim
31 words
A method according to claim 1, wherein the electrically conductive members comprise electrical connecting portions, and further comprising the step of metallurgically connecting these electrical connecting portions to electric circuit parts.
Claim 6
Dependent Claim
22 words
A method according to claim 1, wherein the holding member is resin having its hardness varied by the application of light thereto.
Claim 7
Independent Claim
180 words
A method of manufacturing an electrical connecting member having a holding member formed of an electrically insulative material, and a plurality of electrically conductive members provided in a mutually insulated state in the holding member, one end of each of the electrically conductive members being exposed on one surface of the holding member and the other end of each of the electrically conductive members being exposed on the other surface of the holding member, said method comprising the steps of: providing photosensitive resin as the holding member on a base body; exposing the photosensitive resin to light by the use of a mask provided with light intercepting portions, light transmitting portions and light attenuating portions; developing the exposed photosensitive resin to thereby form apertures in which portions of the base body are exposed in the photosensitive resin and through-holes; removing the portions of the base body exposed in the apertures by etching to thereby form recesses; filling the apertures and the recesses with a material for the electrically conductive members and leaving the through-holes empty; and removing the base body.
Claim 8
Independent Claim
