PROBLEM TO BE SOLVED: To lower inductance and resistance. SOLUTION: A coil spring supporting hole 5 is provided in an intermediate portion of two integrated insulating plates 4, each of which has an outer surface provided with a needle body supporting hole 6 having a rectangular cross-section, so as to contain a compression coil spring 7 in the coil supporting hole 5, and a pair of T-shaped conductive needle bodies 8 obtained by pressing plate material are supported by the needle body supporting holes 6 so as to freely project and retract through the needle body supporting holes 6, respectively. The T-shaped conductive needle bodies have step portions 8c between which the compression coil spring is provided, and have embedded ends provided with engaging portions 8d engaged with each other against elastic bias force. The distance b between the center of axle of the coil spring supporting hole and a needlepoint portion 8e is made larger than the distance a between the center of axle of the coil spring supporting hole and a step portion 8c, and the needlepoint portion 8e is pressed against a contact body, so that a moment acts in such a direction as to press against the engaging portions 8d. This enables the engaging portions 8d to always slide over each other. As a result, inductance and resistance can be lowered by passing a transmission signal without a coil spring. This enables an application to transmission of a high-frequency signal. COPYRIGHT: (C)2008,JPO&INPIT
