Abstract

Since the invention makes a structure in which bent portions 18A, 18B of grounding pieces 16A, 16B of a center conductor side grounding portion 11 and bent portions 22A, 22B of grounding pieces 20A, 20B of an outer conductor side grounding portion 13 are connected to each other by joint portions 12A, 12B, solders contact portions 17A, 17B and 21A, 21B of the center conductor side grounding portion 11 and the outer conductor side grounding portion 13 respectively to a center conductor grounding side conductor portion F and an outer conductor grounding side conductor portion G of an antenna element of a glass board face 25a, and then breaks off the joint portions 12A, 12B and thereby separates the center conductor side grounding portion 11 and the outer conductor side grounding portion 13 from each other, the invention makes it possible to stably attach a center conductor and an outer conductor of the fore-end portion of a coaxial cable to the same positions as determined in a terminal for coaxial cable and to accurately and stably mount the center conductor and the outer conductor on the same positions as determined also with respect to the interval between them on a mounted object.
