A flat conductor wire in a U-phase first slot (SU1) of a first group block (B1) and a flat conductor wire in a U-phase second slot (SU2) of a second group block (B2) form an outer circumference base unit (11). A flat conductor wire in a U-phase second slot (SU2) of the first group block (B1) and a flat conductor wire in the U-phase first slot (SU1) of the second group block (B1) form an inner circumference base unit (12). The inner circumference base unit (12) is located inside the outer circumference base unit (11). A coil end portion at one end of the inner circumference base unit (12) and a coil end portion (A) side at one end of the outer circumference base unit (11) are bent toward the rotor (42) side with respect to an in-slot conductor portion (SA, SB) in the stator core (15). The coil end portion (A) side at one end of the inner circumference base unit (12) and the coil end portion (A) side at one end of the outer circumference base unit (11) are located further toward the axis of the rotor (42) than an inner peripheral surface of the stator core (15).
