Summary:PROBLEM TO BE SOLVED: To reduce cost by facilitating positioning of a terminal plate, making hard to create a gap between terminal plates adjacent each other, and reducing material loss of the plate material forming the terminal plates. SOLUTION: A plate material X1 is formed in a shape that one contact piece 18c2extends from a base end part end edge of a contact retaining piece 18d toward another contact piece 18c1. Since the contact piece 18c2does not stick out after bending like in a conventional example and does not have a gap on a center line of width standard of a first terminal plate 18, positioning in storing in a terminal storage 14 of a body 5b is facilitated. When the first terminal plates 18 are arranged in a width direction and set in a part feeder in manufacturing, since the contact piece 18c2does not hit adjacent terminal plate 18, position shift hardly happens. Blanking efficiency is improved of the material and its loss is reduced to reduce the cost. COPYRIGHT: (C)2003,JPO
