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.

說明書

The thickness of the crack suppressing layer 7 is made thinner than the thickness of the insulator 3. More specifically, the thickness of the crack suppressing layer 7 may be 0.10 mm or more and 0.20 mm or less. When the thickness of the crack suppressing layer 7 is 0.10 mm or more, the mechanical strength of the crack suppressing layer 7 is increased, and therefore it is easy to suppress the occurrence of a fracture in the crack suppressing layer 7 due to bending. Further, when the thickness of the crack suppressing layer 7 is 0.20 mm or less, the stress applied to the plating layer 4 in the bending or the like of the high frequency signal transmission cable 1 (the stress applied to the plating layer 4 resulting from bending of the crack suppressing layer 7 following the bending of the high frequency signal transmission cable 1) is small, and therefore the plating layer 4 is easily suppressed from cracking.
