Zusammenfassung:	PROBLEM TO BE SOLVED: To evenly heat a winding for a short time in a series of processes in which the winding is impregnated with varnish and is hardened in manufacturing of a rotary electric machine. SOLUTION: In an induction heating method of the winding for the rotary electric machine using power supply of a frequency which is higher than commercial power supply, a heating coil is used, wherein the heating coil is wound so that a direction perpendicular to a central axis of a radial direction of an annular body may become an axial direction.
