Patent ID: 8378217

Claim:
A differential signal cable, comprising; two insulated wires arranged parallelly in a contact, each of said two insulated wires comprising a conductor and an insulator jacketing the conductor; a fusion layer provided on the surface of each of said two insulated wires; a drain wire placed longitudinally in a recess created in the interstice between said two insulated wires; and a shield tape lapping around said two insulated wires and said drain wire together, wherein a surface of said insulator of each of said two insulated wires is partially deformed so as to have a flat portion and said two insulated wires are fused to each other at said flat portions, wherein said insulator comprises a foamed material and said two insulated wires are fused to each other through a heat-melt of said fusion layer, and wherein said fusion layer comprises the same material as said insulator having a degree of foaming lower than that of said insulator.
