PROBLEM TO BE SOLVED: To connect a central contact to the inner conductor of the coaxial cable in a shape which makes no noise, without requiring skill. SOLUTION: The central contact 3, which is supported in the inner center of the shell 1 through an insulating material 4, is provided, from one end toward the longitudinal direction, with an inserting hole 9 in which an inner conductor N of the coaxial cable is inserted and connected. The deep inner part 9a of the inserting hole 9 is made small diameter so as to have the inner conductor N fitted closely and the opening side 9b of the inserting hole is made larger diameter than the deep inner part 9a. A solder injecting hole 10 is provided at the barrel part of this larger diameter part 9b, and as the inner conductor N is positioned at the inner central part of the insertion hole 9 by the smaller diameter part 9a of the insertion hole 9, soldering is made in that state.
