Abstract:
1. A differential transmission signal cable comprising; one pair of signal wires including a central conductor covered by an insulating layer; a drain wire arranged along said signal wires; and an outer conductor for covering said signal wires and said drain wire, wherein: said drain wire is covered by a covering film made of a semi-conductive material having flexibility and containing an electrically conductive filler, an outer diameter of said covering film for covering said drain wire is smaller than a diameter of each of said signal wires, said semi-conductive material is made of such a material that the electrically conductive filler and a smoothening agent are kneaded in a resin, the smoothening agent being less than or equal to several weight % with respect to the resin, and secant modulus of said semi-conductive material is equal to 100 MPa to 600 MPa.
