摘要： A wire harness has less differences of the amount of deflection caused by the self weight when the wire harness is constructed by arranging the plurality of the electric wire having the different cross-sectional area of the conductor. A wire harness has first and second electric wires arranged side by side in a direction intersecting an axial direction of the electric wires. Each of the first and second electric wires includes a conductor with a plurality of elemental wires, the second electric wire has a larger conductor cross-sectional area than the first electric wire has, the second electric wire has the larger outer diameter of the elemental wires composing the conductor than the first electric wire has, and the second electric wire contains a same or smaller number of elemental wires composing the conductor in comparison with the first electric wire.

摘要： A wiring harness comprises a first covered electric wire, and a second covered electric wire. The first covered electric wire comprises a first electric wire conductor made of aluminum or an aluminum alloy and an insulator covering the first electric wire conductor. The first electric wire conductor comprises a wire strand of a plurality of elemental wires twisted together, and has a flat portion where a cross-section of the wire strand intersecting an axial direction of the wire strand has a flat shape. The second covered electric wire comprises a second electric wire conductor made of copper or a copper alloy and an insulator covering the second electric wire conductor. The second electric wire conductor has a lower flatness and a smaller conductor cross-sectional area than the first electric wire conductor of the first covered electric wire.

摘要： An aluminum alloy contains at least 0.03 mass % and at most 1.5 mass % of Mg, at least 0.02 mass % and at most 2.0 mass % of Si, and a remainder composed of Al and an inevitable impurity, a mass ratio Mg/Si being not lower than 0.5 and not higher than 3.5. In a transverse section of the aluminum alloy wire, a rectangular surface-layer void measurement region having a short side of 30 μm long and a long side of 50 μm long is taken from a surface-layer region extending by up to 30 μm in a direction of depth from a surface of the aluminum alloy wire. A total cross-sectional area of voids present in the surface-layer void measurement region is not greater than 2 μm2.

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.
