ABSTRACT:
According to a production method for a structure of a contact point of a terminal piece, it is possible to heighten the durability of the terminal piece by thickening the contact point without raising material cost and processing costs. Materials for a copper plate (20) of a circumferential wall portion (18) of a contact point (16) are gathered and pressed toward substantially the center of a top portion (17). The materials are moved toward substantially the center of the top portion (17), so that the thickness of the top portion (17) becomes larger by a thickness of .alpha. than the thickness (T) of the copper plate (20). The top portion (17) is formed to be thicker than the circumferential wall portion (18).
