The stator includes a plurality of cores arranged in a circumferential direction, and coils wound around the cores. A lead wire drawn out from the coils is arranged to extend, radially outside of the one of the rotors, from the corresponding core to a position on the one axial side of the one of the rotors, and is connected to the busbar at the position. The busbar unit is housed in the housing.
