An electric wire includes a flat stranded conductor having a flat shape in cross sectional view and configured by a plurality of conductive wires each having a wire diameter of 1.2 mm or less and which are stranded to each other, and a flat covering portion that is an insulator and covers the flat stranded conductor. The flat covering portion has a uniform elongation of 43.5% or more.

A bus bar electric wire includes a flat conductor which is formed of aluminum and inevitable impurities, and which has a cross-section of a substantially rectangular shape. An area of the cross-section is 15 mmor more and 240 mmor less. The flat conductor includes a bent portion having a predetermined bending R in a plane direction of the flat conductor, and a conductor part that is an outermost side of a bend in the bent portion has a plate width being set within a range satisfying uniform bending of the conductor part.

A flat conductor wire includes a flat conductor made of aluminum containing inevitable impurities. A cross section of the flat conductor orthogonal to a longitudinal direction of the flat conductor has a rounded corner portion, a radius of curvature of the corner portion being equal to or greater than one fourth of a thickness of the cross section of the flat conductor. A width of the cross section of the flat conductor is equal to or smaller than 60&#x3b5;/(1&#x2212;&#x3b5;), &#x3b5; being a uniform elongation of the flat conductor.
