The stator core is formed of laminated core plates and has crimped portions in boundaries between a yoke and bases of teeth. The crimped portions are spaced at equal intervals in a circumferential direction of the stator core. Coil ends are laced by the string in such a way that the string is not passed through teeth spaces having the crimped portions disposed outward thereof in a radial direction of the stator core, but passed through the teeth spaces that are located adjacently on opposite sides of each of the teeth spaces having the crimped portions disposed radially outward thereof and also passed through at least one of any two adjacent of the teeth spaces.
