摘要： The present invention provides an automotive rotary electric machine and a stator manufacturing method that is used therefor in which radial widths of return portions of winding assemblies that constitute coil ends of a stator winding that are stacked in a radial direction are made sequentially greater in an outer layer, an inner layer, and an intermediate layer to enable mounting into a stator core of winding assemblies that use wires that have large cross-sectional areas, to suppress bulges in a radial direction of coil end groups, and to enable interference with a housing and a rotor to be avoided. The stator winding has winding assemblies that are disposed in a stator core so as to be stacked in three or more layers in a radial direction such that slot-housed portions line up in single columns in a slot depth direction inside slots, and radial widths of return portions of the winding assemblies that are mounted so as to be stacked in a radial direction are made sequentially narrower in order of return portions of a winding assembly that is positioned centrally, return portions of a winding assembly that is positioned on an inner circumferential side, and return portions of a winding assembly that is positioned on an outer circumferential side.
