Abstract
A stator includes a yoke extending in a circumferential direction about an axis line, a tooth extending from the yoke in a first direction toward the axis line, and a coil wound around and fixed to the tooth. The yoke has an inner wall surface facing the axis line. The tooth has a root part connected to the yoke. The inner wall surface of the yoke is a flat surface extending from an end of the root part of the tooth in the circumferential direction to an inner circumferential side relative to a plane passing through the end and perpendicular to the first direction.
