High frequency signal transmission cable

A high frequency signal transmission cable, comprising:

• a conductor;
• an insulator provided over a periphery of the conductor;
• a plating layer provided over a periphery of the insulator;
• a crack suppressing layer comprising a non-cross-linked polyethylene, the crack suppressing layer being 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;
• a first braided shield disposed on an outer surface of the plating layer;
• and
• a second braided shield disposed on an outer surface of the first braided shield,
• wherein the second braided shield comprises metal wires having an outer diameter with a different size from an, outer diameter of metal, wires of the first braided shield,
• wherein the plating layer is adhered tightly to the roughened outer surface of the crack suppressing layer such that the crack suppressing layer is configured to move with the plating layer in a longitudinal direction of the cable relative to a bending of the insulator,
• wherein a thickness of the crack suppressing layer is less than a thickness of the insulator,
• wherein the thickness of the crack suppressing layer is 0.10 mm or more and 0.20 mm or less,
• wherein the crack suppressing layer is assembled with respect to the insulator to freely move relative to the insulator, and
• wherein, when moving, the crack suppressing layer remains in contact with the insulator with no space therebetween.
