PURPOSE: To lengthen a contact piece and reduce a spring constant without increasing the outer periphery length and the vertical size by fixing the end section of the contact piece on a board side to a anchor piece.
CONSTITUTION: When the contact piece 2 of a conducting member 5 and the end section of a terminal piece 3 on a board 1 side are integrally fixed to an anchor piece 4, the end section of the contact piece 2 apart from the board 1 has elasticity in the thickness direction of the board 1, and the length of the contact piece 2 can be increased by decreasing the outer periphery length of the board 1. On one of adjacent sides of the board 1, the distance of the terminal piece 3 to the anchor piece 4 is smaller than the distance of the contact piece 2 in the thickness direction of the board 1, the anchor pieces 4 of adjacent sides are brought into no contact with each other in corner sections of the board 1, and the electric insulation state between the contact pieces 2 is secured in the corner section.
