Abstract: A method of manufacturing a stator for a rotary electric machine. The stator includes a stator core and coil segments including protruding portions that are twisted by a first twist angle, except small-twisted protruding portions which are ones of the protruding portions and which are twisted by a second twist angle that is smaller than the first twist angle. The method is executed by using a tubular-shaped tool having engaging grooves having a first groove width, except small-twisting engaging grooves which are ones of the engaging grooves and which have a second groove width that is larger than the first groove width. The tubular-shaped tool is spirally rotated relative to the stator core, with the protruding portions being inserted in the engaging grooves except the small-twisted protruding portions that is inserted in the small-twisting engaging grooves, whereby the protruding portions including the small-twisted protruding portions are concurrently twisted.
