Abstract
A stator includes a stator core and a coil. The stator core includes an annular yoke portion and a plurality of teeth that are annularly aligned. The plurality of teeth protrude from the yoke portion. Slots are constituted respectively by two adjacent teeth of the plurality of teeth. Insulating resin fills the slots of the stator. The coil includes a winding wire passed through the slots and wound around the teeth. The winding wire includes a core wire forming a conductive path and a covering portion covering the core wire. In each of the slots, the insulating resin completely fills a gap between an inner wall of the tooth and the covering portion.
