A motor includes a rotor about a central axis, a stator having coils, and bypass bus bars connecting in-phase coils. The coils include a first-phase coil and a second-phase coil. The bypass bus bars each include a first terminal part and a second terminal part. The first-phase coil and the second-phase coil are adjacent to each other in a slot in which a first lead wire extending from the first-phase coil and a second lead wire extending from the second-phase coil are each drawn to one side in an axial direction. The first lead wire is connected to the first terminal part of one of the bypass bus bars. The second lead wire is connected to the second terminal part of another of the bypass bus bars. The first terminal part and the second terminal part are aligned in a circumferential direction and shifted in a radial direction.
