Abstract: A coil includes a first coil layer and a second coil layer which is formed by winding a rectangular conductor. A side surface of the second coil layer contacts a side surface of the first coil layer in a second direction that is perpendicular to a radial first direction where the rectangular conductor overlaps. In the first coil layer, a second portion contacts a first portion. In the second coil layer, a fourth portion contacts a third portion. An outer surface of the third portion is closer to an outer peripheral side in the first direction than the outer surface of the first portion, and is closer to an inner peripheral side in the first direction than an outer surface of the second portion. An outer surface of the fourth portion is closer to the outer peripheral side in the first direction than the outer surface of the second portion.

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.

Abstract: A rolling bearing has an inner ring attached to a rotating shaft out of contact with a first end surface, and an outer ring is fitted onto an inner peripheral surface of a housing in contact with the first end surface. A sliding element is provided between a second end surface and the first end surface. A retaining portion is provided between the sliding element and the first end surface. A biasing portion is provided between the retaining portion and the first end surface to bias the retaining portion toward a second side in a lamination direction. The rotating shaft, the housing, the inner ring, the outer ring, a rolling element, the sliding element, the retaining portion, and the biasing portion are formed of a conductive material. The rotating shaft and the housing are electrically connected by the sliding element, the retaining portion, and the biasing portion.
