Summary:An axial-gap-dynamoelectric machine includes resin bobbins having positioning protrusions, and a stator core including a base yoke having a plurality of tooth holes and positioning holes. In each tooth hole, a circumferential length of a tooth-hole-radial-direction-outer-end surface is larger than a circumferential length of a tooth-hole-radial-direction-inner-end surface. Each of the plurality of teeth has a columnar shape in which a circumferential length of a tooth-upper surface is larger than a circumferential length of a tooth-bottom surface. The positioning protrusions are inserted in the positioning holes, and press the teeth against the base yoke inward in the radial direction such that the tooth-bottom surface is brought into contact with the tooth-hole-radial-direction-inner-end surface and the tooth-oblique surface is brought into contact with the tooth-hole-circumferential-direction-end surface.
