摘要

A high frequency signal transmission cable includes a conductor, an insulator provided over a periphery of the conductor, a plating layer provided over a periphery of the insulator, and a sheath provided over a periphery of the plating layer. A crack suppressing layer is provided between the insulator and the plating layer, in such a manner as to remain in contact with the insulator while being provided with the plating layer over an outer surface of the crack suppressing layer. The crack suppressing layer suppresses the occurrence of a cracking in the plating layer by bending while moving in a longitudinal direction of the cable relative to a bending of the insulator.
