A motor includes a rotor rotatable about a central axis, and a stator opposing the rotor in a radial direction. The stator includes an annular core back and a stator core including teeth extending from the core back to one side in the radial direction. The stator core includes a laminated steel sheet in which electromagnetic steel sheets are laminated in a direction of the central axis. Each of the electromagnetic steel sheets includes a caulking dowel portion to which the adjacent electromagnetic steel sheets are connected by press-fitting. The caulking dowel portion includes a protrusion protruding from the core back to another side in the radial direction.
