The stator core includes a plurality of slots opening on the inner circumferential side and the slots are each formed as an open slot with a width of an inner circumferential-side opening thereof ranging along a circumferential direction set substantially equal to or greater than a width of a bottom side measured along the circumferential direction. The stator further includes a slot insulator disposed between inner wall of each of the slots at the stator core and the stator coil and a holding member constituted with a nonmagnetic material and inserted in each of the slots at the stator core so as to hold the slot insulator between two side surfaces present along the circumferential direction at the slot. The stator is formed by winding the stator coil through the plurality of slots.
