摘要： PROBLEM TO BE SOLVED: To enhance a shielding effect, and provide an inexpensive twisted-pair cable.
SOLUTION: The shielding layer 4 in this twisted-pair cable is equipped with the inner shielding layer 41 installed on the outer periphery of the press winding layer 3, and the outer shielding layer 42 installed at the outer periphery of the inner shielding layer 41. The inner shielding layer 41 is composed of a plastic tape laminated with a metal foil on one side, in which the metal foil of its own is wound up outward at a lap of, for instance, 1/4 or more, while the outer shielding layer 42 is composed of a plastic tape laminated with the metal foils on both sides and wound up at a lap of, for instance, 1/4 or more, as if to cover a side edge part of the plastic tape laminated with the metal foil on one side.
