Abstract
A differential signal transmission cable includes an insulation layer extending in a longitudinal direction of the differential signal transmission cable, a pair of signal lines extending in the longitudinal direction and buried inside the insulation layer, an intermediate layer covering an outer circumferential surface of the insulation layer, a shield, and catalyst particles. The shield includes an electroless plating layer covering an outer circumferential surface of the intermediate layer. The catalyst particles are dispersed between the intermediate layer and the electroless plating layer.
