Abstract: A first portion of an insulator is provided on a first region of an end surface of a tooth. A second portion of the insulator is provided on a second region of the end surface of the tooth so as to be separated from the first portion in a circumferential direction. A third portion of the insulator is connected to fourth side ends of the first portion and the second portion in a radial direction. A coil includes a crossing portion in a coil end. A stator includes an insert body in a housing space. The insert is made of a material having a higher thermal conductivity than a material forming the insulator.
