An object of the invention is to reduce a stress on an insulating coating on a conductor segment for a stator coil. The conductor segments are bent simultaneously by a head bending apparatus and leg bending apparatus, both provided with a respective disc guide member for guiding the inner most conductor segments along the circumferential direction. Particularly, the disc guide member 16b (for example, may have a permanent magneto built-in) is fixed at the lower surface of the stator core 1. The disc guide member 16b almost touches the inner circumferential surface of the larger segment 331. During bending the tip of the leg portions 33c on the bending jig 543, the disc guide member 16b prevents the leg portions 33c of the larger segments 331 from inclining toward the inner radius direction, thereby bending and extending the linear portions 33c along the circumferential direction.
