Summary:An axial-gap-dynamoelectric machine that allows magnetic fluxes to flow efficiently while enhancing assemblability of pressed powder teeth to a base yoke is provided. An axial-gap-dynamoelectric machine X includes resin bobbins 9 having positioning protrusions 9c, and a base yoke 5 having a plurality of tooth holes 6 and positioning holes 5a. In each tooth hole 6, a circumferential length of a tooth-hole-radial-direction-outer-end surface 6c is larger than a circumferential length of a tooth-hole-radial-direction-inner-end surface 6a. Each of the plurality of pressed powder teeth 8 has a columnar shape in which a circumferential length of a pressed-powder-tooth-upper surface 8b is larger than a circumferential length of a pressed-powder-tooth-bottom surface 8a. The positioning protrusions 9c are inserted in the positioning holes 5a, and press the pressed powder teeth 8 against the base yoke 5 inward in the radial direction of a stator core 7 such that the pressed-powder-tooth-bottom surface 8a is brought into contact with the tooth-hole-radial-direction-inner-end surface 6a and the pressed-powder-tooth-oblique surface 8c is brought into contact with the tooth-hole-circumferential-direction-end surface 6c.
