PROBLEM TO BE SOLVED: To prevent electrical characteristics from varying, by securing stable contact of a connector pin with a tube at all times. SOLUTION: One end 30 of a compression coil spring 3 abuts on a bottom surface 24 of a base end of a connector pin 2, and the other end 32 thereof abuts on a bottom surface 10 of a tube 1. The coil spring 3 has a projection 34 axially projecting from its end 30, and the end of the projection 34 abuts on the bottom surface 24 of the base end of the connector pin 2 at a bias position S radially biased from the center axis C of the connector pin 2. A moment M acts on the connector pin 2 so as to incline its center axis C relative to the tube 1 by a resilient force F of the coil spring 3 acting on the bias position S. Thus, a peripheral portion X of the base end part 20 of the connector pin 2 is pressed against an inner surface of the tube 1 by the moment M.
