To provide a reliable stator for motor where adherence among thermoplastic mold resin, winding, and an insulator is satisfactory, without disorder of winding, even with respect to high molding pressure by thermoplastic mold resin.

For this mold stator 1, the stator for motor comprises a laminated core 4, an insulator 3 attached to the core, and a self-welded winding 2 provided on the insulator 3 is integrally molded of thermoplastic mold resin reinforced by glass fibers, and is thermoplastic polyester resin where the thermoplastic mold resin 5 and the insulator 3 are reinforced by fibers.
