A communication cable includes an insulation electric wire including a conductor having tensile strength of 400 MPa or more and a cross-sectional area of 0.22 mm.sup.2 or less and a covering layer covering the conductor and being formed of an insulating material, and a sheath covering an outer periphery of the insulation electric wire and being formed of a resin composition containing crystalline polyolefin. A tensile elastic modulus of the sheath is 500 MPa or less, and a mass increase rate of the sheath is less than 50 mass % in a plasticizer migration test involving exposure in an atmosphere at 105? C. for 3,000 hours. Characteristic impedance of the communication cable is 100?10?.

A differential transmission cable includes a pair of signal lines, an insulation covering the pair of signal lines, and a shielding tape that includes a conductor layer and an insulation layer formed on one surface of the conductor layer and is helically wound around the insulation. The diameter of the signal line is thinner than at least 30 AWG (American Wire Gauge), and differential characteristic impedance is not less than 80 and not more than 120.

Provided herein is a multi-core cable through which positions of a plurality of insulated conductors and a plurality of non-insulated conductors in a cross section in a longitudinal direction are changed and a likelihood of transmission performance being reduced is low. A multi-core cable includes n conductor bundles.

A cable having low values for resistance, inductance, and capacitance. The cable includes a plurality of conductors for each signal or leg, which may be configured as a braid of three subsets of braids of bonded pairs of insulated conductors. The bonded pairs may be twisted or untwisted, in close proximity such that inductance is reduced via magnetic field cancellation. Each leg may be separate and parallel, rather than interwoven or braided together, increasing the distance between the two signals and reducing capacitance. The legs may be positioned close to each other, such that their magnetic fields cancel to further reduce inductance.
