A stator for an inner rotor type motor includes a stator core 1, insulating members 10 and winding wire 3, 4. The stator core 1 includes: four divisional core elements 6 each integrally formed by setting up one tooth 2 to one yoke portion 8; and four divisional yoke elements 7. A rotor opening 11 is formed on top portions of the teeth 2 by arranging the divisional core elements 6 so that the teeth 2 are radially disposed. Four slots 9 are formed by respectively arranging the divisional yoke elements 7 between the yoke portions 8 of the adjacent divisional core elements 6. The winding wire 3, 4 is wound on the teeth 2. An inner surface of each yoke portion 8 is substantially perpendicular to the central axis of the corresponding tooth 2 while the insulating member 10 is provided on side surfaces of each tooth 2.
