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.

More specifically, the outer diameters of the metal wires to be used in the first braided shield 5a may be 0.08 mm or more and 0.14 mm or less in order to achieve the high bendability and the micro fine mesh size. Further, the outer diameters of the metal wires 12 to be used in the second braided shield 5b may be 0.10 mm or more and 0.16 mm or less in order to achieve the high bendability and the low conductor resistance. Further, in order to allow the first braided shield 5a and the second braided shield 5b to have their respective distinct functions, the outer diameters of the metal wires 11 to be used in the first braided shield 5a may be not larger than 90% of the outer diameters of the metal wires 12 to be used in the second braided shield 5b.
