A motor includes a motor body, a housing, a heat sink, a controller, a connector, and a cover. The heat sink includes two arm portions each extending radially outward. The connector is held between the two arm portions. The heat sink and the connector include a cover joint portion extending all the way around surfaces of the heat sink and the connector along a circumferential direction, is loop-shaped, and surrounds the controller, when viewed in an axial direction. The cover is joined to the cover joint portion. The connector includes a connector outside surface exposed between the two arm portions, and including circumferential end portions adjacent to the arm portions and overlapping with an imaginary line joining distal ends of the two arm portions or located radially inward of the imaginary line when viewed in the axial direction.
