PROBLEM TO BE SOLVED: To improve motor performance, by enhancing the occupying factor of a winding in a slot part. SOLUTION: A laminated core 1 is formed by a teeth part 3, a back teeth part 4, and a slot part 5, a width dimension W of the teeth part 3 is formed so as to be gradually decrease, in the direction toward a stator internal peripheral side from a stator external peripheral side. As a result, the slot part 5 is formed into a shape of substiantially a parallelogram or a rectangle, when a winding 2 is wound, its closeness can be generated, and enhances the winding 2 in its occupancy factor in the slot part 5.
