Abstract
A stator includes a yoke, teeth connected to the yoke, and coils including plate-shaped conductive wire and mounted on respective teeth. Each coil includes a wound part, a first and second terminals. The wound part is wound around the tooth n turns (n is an integer equal to or greater than 2). The wound part satisfies a relationship represented by Ak<Bk, where Ak is a height of a first section in an axial direction of the tooth, and Bk is a width of a second section in a circumferential direction of the tooth. The first and second sections are sections in k-th turn (k is an integer that satisfies 1≤k≤n) of the coil. The first section is along an axial end surface of the tooth. The second section extends from an end of the first section along a circumferential end surface of the tooth.
