PROBLEM TO BE SOLVED: To enable to remove radiation noises generated from a pair of core wires and external noises coming into the pair of core wires from the outside of a communication cable, in the communication cable in which a plurality of pairs of core wires are bundled. SOLUTION: The cable comprises a bundle of core wires in which a plurality of pair of wires 11 electrically insulated are bundled and a first covering material 21a and a second covering material 21b which are constructed by laminating at least a magnetic layer 23 and a conductor layer 25 and are arranged so as to contact all pair of wires 11 constituting the bundle of core wires. By this constitution, the conductor layers 25 constituting the first covering material 21a and the second covering material shield noises. Then, even if a gap is generated in the conductor layers 25 and noises are leaked, the magnetic layers 23 absorb the noises. COPYRIGHT: (C)2005,JPO&NCIPI
