PURPOSE: To enable a plated plastic member achieving contact of the plated plastic member with a conductive member to be bonded to the conductive member by a method wherein the conductive member such as a vinyl wire or the like is inserted into a conductive member inserting part of the plated plastic member in a process wherein the plated plastic member is thermally contracted.

CONSTITUTION: A position of a conductive member 2 such as a vinyl wire or the like is fitted to a position of a conductive member inserting part 2 of a plated plastic member 1. Then, the conductive member 2 is advanced to a position exceeding a recessed part 3a, and thereafter a forcively fitting member 5 is inserted from an opening part 4a. The fitting member 5 is forcively fitted into the recessed part 3a via the conductive member 2 such as the vinyl wire or the like, and the plated plastic member 1 is brought into contact with the conductive member to be bonded thereto. Further, though all the plated plastic member 1 may be formed by plating, it suffices for the purpose that at least the conductive member inserting part 3 of an inside and a part of the plated plastic member on a side in contact therewith are plated (for example, silver plated.).
