Abstract: A first coil is formed by winding a first part of a rectangular wire in a spiral shape and is provided to a first tooth. A second coil is formed by winding a second part of the rectangular wire in a spiral shape and is provided to a second tooth. The second coil is wound in the same direction as the first coil. A crossover wire is formed by a third part of the rectangular wire and connects the first and second coils in series. The third part of the rectangular wire is between the first and second parts and all three parts are continuous. The crossover wire includes a twisted portion that is twisted in an outer circumferential direction of the third part and a non-twisted portion. A first length of the twisted portion is equal to or less than a second length of the non-twisted portion.
