A method for manufacturing a resin molded stator according to one preferred embodiment of the present invention includes steps of: preparing a straight winding core in which neighboring partial core backs are coupled together by a joint; bending the straight winding core at a plurality of joints and causing distal ends of a plurality of teeth to face an outer peripheral surface of a columnar core metal to thereby obtain a core metal assembly in which a stator is mounted on the core metal, and arranging the core metal assembly in a mold; injecting a resin into the mold, covering at least windings of the respective teeth with the resin, and curing the resin; and removing the stator molded with the resin from the mold and the core metal, wherein the core metal includes a plurality of ribs that project radially outward from the outer peripheral surface, the number of the ribs being three or more and less than the number of the teeth, each of the plurality of ribs extends parallel to a center axis, and in the core metal assembly, each of the plurality of ribs is located in a gap between the distal ends of the teeth adjacent to each other.
