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 covered electric wire contains a conductor and an insulation covering which covers an outer surface of the conductor. The covered electric wire has a flat portion where a cross section of the conductor intersecting an axial direction of the covered electric wire has a flat shape which has a larger length in a width direction. The insulation covering contains, in the cross section of the flat portion, plane regions which contains, at the surface thereof: a width-directional region along the width direction; and a height-directional region intersecting the width direction. The insulation covering contains a region having a rounded shape having a radius at the junction between the width-directional region and the height-directional region, and the covered electric wire satisfies a relationship of R>t between the radius R and a thickness t of the insulation covering at the plane region. The wire harness contains the covered electric wire.

摘要： An electric wire conductor includes a wire strand having a plurality of elemental wires twisted together. The wire strand includes a deformed part in which a cross-section of the wire strand intersecting an axial direction of the wire strand is formed into a flat shape in which a width of the cross section is larger than a height of the cross section, and an entire outer periphery of the cross section is formed as an outward curve. In the cross-section of the deformed part, the elemental wires have deformation ratios from a circle of 70% or lower at an outer peripheral part facing the outer periphery of the deformed part than at a center part located inside the outer peripheral part.
