Electric heating member

Abstract

Abstract PURPOSE:To prevent the breaking of wiring due to the shunting of a current by successively covering the contact part of a heating member with a material to be worked with a coating film having specified resistivity and a specified contact angle to the melt of a metal consisting essentially of one out of lead and tin. CONSTITUTION:At least the contact part with a lead wire on the surface of a base material consisting of a conductive material is covered with a coating film consisting of a material having resistivity of >=100 times that of the base material and >=10 deg. contact angle to the melt of a metal consisting essentially of one out of lead and tin. Since at least the contact part of the heating member with the lead wire of an IC is thus covered with the insulating coating film having poor solder wettability, the breaking of wiring due to the shunting of a current from the heating member to the wiring of the substrate and the deposition of solder on the heating member are prevented.
