Zusammenfassung:	An object of the invention is to provide a method for manufacturing a stator of a rotating electric machine that can reduce the size of a coil end. According to the invention, a method for manufacturing a stator, which includes a stator core and a stator coil to which ends of a plurality of substantially U-shaped segment coils inserted into slots of the stator core are connected, includes twisting the end of the segment coil using a twisting jig 600. In the twisting, in a state in which the end of the segment coil is inserted into a groove portion 610 of the twisting jig, an edge portion 620 forming a part of the groove portion 610 is used as a twisting fulcrum, and a load is applied to the segment coil to forma press trace of the edge portion on the segment coil.
