Abstract
In a rotary electric machine according to the present invention, an armature winding includes a plurality of distributed winding bodies that are each produced by winding a single conductor wire that is insulated, that is jointless and continuous, and that has a constant cross-sectional area perpendicular to a longitudinal direction, the conductor wires include first through third coil end portions that link first through fourth rectilinear portions and first through fourth rectilinear portions, and are formed such that radial widths w′ of the first through fourth rectilinear portions are wider than radial widths w of the first through third coil end portions.
