Patent ID: 8440910

Claim:
A differential signal transmission cable comprising: two conductor wires disposed to be parallel with each other; a flat insulating member collectively covering the two conductor wires, the insulating member having flat portions facing each other in a direction perpendicular to an alignment direction of the two conductor wires to sandwich the two conductor wires; a shield conductor comprising a metal foil tape, the shield conductor wound around an outer periphery of the insulating member; a drain wire provided to contact with the shield conductor at a position corresponding to one of the flat portions, and a jacket jacketing the drain wire and the shield conductor, wherein a ratio of a distance between the flat portions of the insulating member to a distance between both sides of the insulating member in the alignment direction of the conductor wires is 1:2, and a distance between the two conductor wires is smaller than the distance between the flat portions of the insulating member.
