In a cross section in a first direction representing each of directions of protrusion of the teeth from the stator core, a k-th (k is an integer, 1<k<n) turn of each of the coils lies at a center of a range wound with each of the coils onto the teeth in the first direction. The k-th turn of each of the coils is greater in cross-sectional area than each of a first turn and an n-th turn.
