PROBLEM TO BE SOLVED: To dispense with a coupling wire and troublesome soldering in coupling a coaxial cable with a distribution base board by pressing a ground conductor ring of an annulus ring cross section, whose tongue piece is extended from one of end faces, in contact with the external conductor of the coaxial cable in its closely stuck state. SOLUTION: A coaxial cable 21 is so formed that an insulating body 3 and an outer conductor 4 are closely stuck together in order around the central conductor 2 so as to be arranged into a cylindrical shape in the cross section. Ground conductor rings 26a, 26b of an annulus ring cross section which has tongue pieces 28a, 28b extended from one of end faces 27a, 27b respectively around both play ends 5a, 5b on half way of its extension are pressedly contacted so as to be closely stuck to the conductor 4 respectively. The conductor rings 26a, 26b are preferable to be made of same the material as the conductor 4 and have recesses and projections in the inside face of 29a, 29b. As for coupling with a distribution substrate, the ends 2a, 2b of the conductor 2 and tongue pieces 28a, 28b are bent and directly soldered to a coupling pad and a ground pad of the substrate respectively so that the coupling wire is dispensed. |
