A communication cable includes two-core communication wires, a drain wire, and a metal foil collectively covering the two-core communication wires and the drain wire. The two-core communication wires are twisted, and the metal foil is wound around the two-core communication wires with an adhesion strength of 1.21 MPa or more. Preferably, the two-core communication wires are twisted with a twist pitch of 20 mm or more and 60 mm or less. The communication cable further may include a restraint formed of a resin coating extruded around the metal foil or a resin film laterally wound around the metal foil.

Communication cable and wire harness

A bending-resistant communication cable includes a parallel two-core shielded wire that includes a drain wire in a gap between two-core communication wires and is formed by collectively covering the two-core communication wires and the drain wire by an external conductor. Each of the drain wires in a plurality of parallel two-core shielded wire is arranged to face inside of the bending-resistant communication cable. Further, a twist pitch of the plurality of two-core shielded wires is 20 mm or more and less than 100 mm.

An inner conductor of a coaxial cable is electrically connected to a circuit body of a circuit board by means of solder. An outer conductor is electrically connected to a ground body by means of the solder. The inner conductor has a connecting portion connected to the circuit body and a non-exposed portion inside a sheath. A thickness of the connecting portion is equal to or less than 35% of a thickness of the non-exposed portion, and the cross-sectional area of the connecting portion is the same as the cross-sectional area of the non-exposed portion.
