A signal transmission cable includes a conductor, an insulator covering a periphery of the conductor, and a shield layer covering a periphery of the insulator. The shield layer includes a lateral winding shield portion composed of a plurality of metal wires being helically wrapped around the periphery of the insulator to cover the periphery of the insulator, and a batch plating portion composed of a hot dip plating, which is covering a periphery of the lateral winding shield portion. Where a diameter of the metal wire is d and a thickness of the batch plating portion from an outer surface of the metal wire is t, a formula t<0.5d is met over an entire cable circumference. When the signal transmission cable is bent in a U-shape within a range of a bending strain of 35% or less, no cracks occur in the batch plating portion.

Signal transmission cable and cable assembly

A signal transmission cable is provided with a conductor, an insulator covering around the conductor, a shield layer covering around the insulator, a sheath covering around the shield layer, and a plating base layer is provided between the insulator and the shield layer to cover around the insulator. The shield layer has a plating layer provided to cover the plating base layer to be in contact with an outer peripheral surface of the plating base layer. A surface roughness of an outer peripheral surface of the plating layer is less than a surface roughness of an inner peripheral surface of the plating layer.
