摘要： An electric wire conductor is excellent in space saving and flexibility and is less likely to concentrate a load on specific elemental wires, and a covered electric wire and a wire harness contain the electric wire conductor. The electric wire conductor contains a wire strand containing a plurality of elemental wires twisted together. The wire strand has a sector-shaped part in which a cross-section intersecting an axial direction of the wire strand contains either a single edge or two edges touching each other at an apex, and an outward curve connecting the ends of the single edge or the two edges. In the sector-shaped part, the elemental wires having deformation ratios from a circle lower at an outer peripheral part facing an outer periphery of the sector-shaped part than at a center part of the sector-shaped part located inside the outer peripheral part in the cross-section intersecting the axial direction.

摘要： The application discloses a communication cable that includes a twisted pair of insulated wires twisted with each other, and a sheath covering a single one of the twisted pair. The twisted pair is adhered to a portion smaller than an entire inner surface of the sheath. Each of the insulated wires includes a conductor that has a tensile strength of 400 MPa or higher, and an insulation coating that covers the conductor. The communication cable has no conductive shield inside or outside the sheath, and the communication cable has a characteristic impedance of 100±10Ω.
