PROBLEM TO BE SOLVED: To prevent the deformation of a magnetic pole tooth due to the injection pressure at molding, in a method of integrating the bobbin and the core of an armature by injection molding. SOLUTION: A manufacturing method for a stator includes molding bobbins around the magnetic pole teeth 82 of a core 8 integrally by arranging the core 8 equipped with a plurality of magnetic pole teeth 82 projected radially in a molding die 17, and by injecting insulating resin into the molding die 17. The under mold 20 of the molding die 17 is provided with a core presser 27 which contacts with the lower end face 85a of the head 85 of the magnetic pole tooth 82 of the core 8 and supports it.
