An electric wire conductor having both flexibility and a space-saving property. Also provided are a covered electric wire and a wiring harness containing the electric wire conductor. An electric wire conductor contains a wire strand containing a plurality of elemental wires twisted together. The electric wire conductor has a flat portion in which a cross section intersecting an axial direction of the wire strand has a flat shape. Assuming a conductor cross-sectional area of the flat portion as s mmand a vacancy ratio defined as a ratio of vacancies not occupied by the elemental wires in a cross section of the flat portion as v %, the conductor cross-sectional area and the vacancy ratio satisfies v&#x3e;0.29 s+2.0. The covered electric wire contains electric wire conductor and an insulator covering the conductor. The wiring harness contains the covered electric wire.

Electric wire conductor, covered electric wire, and wiring harness

A wire harness includes a functional exterior component, at least one electric wire, and at least one thread. The functional exterior component is shaped into a sheet. The electric wire is disposed on one main surface of the functional exterior component. With the thread the electric wire is sewn on the functional exterior component.

Wire harness and method for manufacturing thereof

An electric wire conductor having both flexibility and a space-saving property, a covered electric wire, and a wiring harness containing such an electric wire conductor. The electric wire conductor contains a plurality of elemental wires twisted together, and has a non-circular portion in which a cross section intersecting an axial direction of the wire strand has a non-circular shape. The cross section of the non-circular portion has a continuous vacancy capable of accommodating two or more of the elemental wires. Further, a covered electric wire contains the electric wire conductor and an insulator covering the electric wire conductor. Furthermore, a wiring harness contains the covered electric wire.
