Abstract
There is provided a winding to be wound at a stator of a rotary electric machine. The winding is produced from a flat wire having a rectangular cross section along a plane perpendicular to a length-wise direction. The flat wire is coated with an electric insulating layer and is bent to have curves at given portions of the flat wire in the length-wise direction. The curves are located on an axial outer side of the stator. The cross section of the flat wire has four corners, among which mutually-adjacent two corners are lager in curvatures than remaining mutually-adjacent two corners. The mutually-adjacent two corners whose curvatures are smaller are positioned on a circumferential outer side of each of the curves and the mutually-adjacent two corners whose curvatures are larger are positioned on a circumferential inner side of each of the curves.
