Abstract
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 includes a non-cross-linked polyethylene 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 entire periphery of a roughened outer surface of the crack suppressing layer. The crack suppressing layer is unadhered to the insulator. The plating layer is adhered to the crack suppressing layer. The crack suppressing layer suppresses an occurrence of a cracking in the plating layer by bending together with the plating layer while being integral and moving with the plating layer in a longitudinal direction of the cable.
