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

In the present embodiment, a non-cross-linked polyethylene is being used as the crack suppressing layer 7. The melting point of the polyethylene is increased by irradiation cross-linking by on the order of 20° C. For that reason, for example, by using an irradiated cross-linked polyethylene as the resin constituting the insulator 3 and using a non-cross-linked polyethylene as the resin constituting the crack suppressing layer 7, it is possible to easily form the crack suppressing layer 7 that can, with the crack suppressing layer 7 remaining in contact with the outer surface of the insulator 3 with no space therebetween, be bent while being moved in the longitudinal direction of the cable 1 relative to the bending of the insulator 3. Note that the resin to be used in the insulator 3 or the crack suppressing layer 7 is not limited to the above described resin.
