Abstract
Each of the coils provided in a stator includes a wire introducing portion where a wire is introduced into a groove, an adjusting portion including the wire wound within the groove, and a plurality of wire layers each of which are aligned adjacent one another along an extending direction of a tooth. Among the plurality of wire layers, wires located on a periphery side-end in the odd-numbered wire layers are separated from an inner circumferential surface of the periphery by a half pitch.
