Abstract: A multi-core cable includes at least two coaxial wire pairs, each of the coaxial wire pairs including two coaxial wires being arranged side by side in contact with each other, each of the coaxial wires including a center conductor, an insulator, an outer conductor and a jacket, the outer conductor including an inner layer portion formed by thin metal wires being helically wrapped, and an outer layer portion formed by a metal resin tape being helically wrapped around the inner layer portion. A wrapping direction of the thin metal wires of the inner layer portion is opposite to a wrapping direction of the metal resin tape of the outer layer portion. An angle in the wrapping direction of the metal resin tape with respect to the wrapping direction of the thin metal wires is in a range of 30° or more but 90° or less. A cross-talk between the coaxial wire pairs is equal to or less than ?40 dB.

Abstract: There is provided a multi-core cable including: first insulated wires; second insulated wires; coaxial wire pairs; and a sheath. The second insulated wires are smaller in diameter than the first insulated wires. The coaxial wire pairs are provided in an even number of pairs. The first insulated wires and the coaxial wire pairs are arranged close to each other on a single circle in a cross section, and the second insulated wires are disposed thereinside. The first insulated wires, the second insulated wires and the coaxial wire pairs are wholly twisted, and then, wholly covered by the sheath.

Abstract: One embodiment provides a multicore cable in which plural coaxial cable pairs are collected. Each coaxial cable pair is formed by twisting together or arranging in parallel two coaxial cables. Each coaxial cable includes a center conductor and an insulator covering the center conductor. The center conductor is a strand of nineteen or more wires or a single wire.

Abstract: A multi-core cable includes a plurality of small diameter coaxial electronic wires arranged on the same circumference, a tape wrapping formed with an electrically conductive resin tape which is wound on the periphery of the plurality of small diameter coaxial electronic wires, and a shield layer covering the periphery of the plurality of small diameter coaxial electronic wires through the tape wrapping.
