摘要 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 18c<SB>2</SB>extends from a base end part end edge of a contact retaining piece 18d toward another contact piece 18c<SB>1</SB>. Since the contact piece 18c<SB>2</SB>does 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 18c<SB>2</SB>does 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
