PROBLEM TO BE SOLVED: To provide an electric motor of which the poor insulation by the resin insulation of the electric motor has been reduced, where a coil is wound around a plurality of magnetic pole teeth extended radially from the yoke of a stator via resin insulation. SOLUTION: In the electric motor, the stator has the plurality of magnetic pole teeth extended radially from the yoke, a slot penetrating in the axial direction of the stator is formed by adjacent magnetic pole teeth, and the coil is wound around the magnetic pole teeth via the resin insulation. The resin insulation has a winding body around which a coil is wound; an outside collar extended in the axial direction of the stator at the outer-periphery side of the stator at the winding body; an inside collar extended in the axial direction of the stator at the inner-periphery side of the stator at the winding body; and a slot insulation section along the inside wall of the slot of the winding body. In this case, a corner escape section is formed at least at one place at the magnetic pole tooth corner of the resin insulation facing an end face side in the axial direction of the stator in the magnetic pole teeth.
