PROBLEM TO BE SOLVED: To provide the stator of an electric motor that normally winds a coil around a resin bobbin fitted to the tooth of the stator in the electric motor, can reduce the size of the electric motor, can improve performance, and has excellent quality. SOLUTION: In the stator of the electric motor, the tooth of the stator in the electric motor is arranged annularly, the resin bobbin is fitted to the tooth for concentrically winding the coil, and the coil is reversely wound at adjacent teeth. In this case, a corner protrusion for normally winding the coil is provided on the slot inner surface of the resin bobbin, the corner protrusion is provided at a position where a slot inner tooth side at one tooth of the resin bobbin fitted to the adjacent teeth crosses a slot inner bottom side, and the corner projection is provided at a position where the slot inner tooth side crosses a slot inner opening side at a slot opening side, for easily performing normal winding to the coil for other teeth, thus winding many coils, miniaturizing the electric motor and improving the performance, and achieving the stator if the electric motor having improved quality.
