A detection part of a temperature detection element is mounted to ends of drawn portions which are further protruded in the axial direction than coil end portions. The detection part and the ends of the drawn portions provided with the detection part are covered with a covering member. The ends of the drawn portions provided with the detection part and covered with the covering member are inserted into a through hole of a wall member which is disposed so as to axially face an axial end face of a stator core. In this case, the detection part is located at a position deeper (on the rear side) than a position of a stator core side opening of the through hole.
