Abstract
Abstract A method for producing an electrical circuit member includes the steps of positioning and arranging first and second electrical circuit parts having plural electrical connecting portions to be spaced and oppose each other, preparing an electrical connecting member having a plurality of electrical conductive members, each of which extends from one side of a holding member of an electrical insulating material therethrough to an opposite side of the holding member and is held in the holding member so that opposing ends of the electrical conductive member protrude from opposite sides of the holding member, and applying an adhesive to at least one side of the electrical connecting member including the electrical conductive members. The electrical connecting member with the adhesive is inserted between the first and second electrical circuit parts, and a pressing force is applied so that the first and second electrical parts contact the ends of the electrical conductive members.
