PROBLEM TO BE SOLVED: To reduce the number of parts and simplify the manufacturing process and reduce the height and the axial dimensions of a coil end while improving the space factor of a coil by simplifying the constitution of a stator. SOLUTION: When arraying U-phase teeth 22 where each annular coil 14 and 15 is arranged only on the other side in its axial direction P, V-phase teeth 24 where each U-phase annular coil 14 is arranged on one side in its axial direction P and each W-phase annular coil 15 is arranged on the other side, and W-phase teeth 26 where each annular coil 14 and 15 is arranged only on one side in its axial direction P, in order in its circumferential direction C, U-phase teeth 22 are projected for one stage relatively by the height equivalent to the thickness of single U-phase annular coil 14 toward one side (the side where each annular coil 14 and 15 does not exist) in its axial direction P, and besides W-phase teeth 26 are projected for one stage relatively by the height equivalent to the thickness of single W-phase annular coil 15 toward the other side (the side where each annular coil 14 and 15 does not exist) in its axial direction P.
