A three-phase motor having a stator in which the dimensions of protrusion of coil end parts in winding coils of individual phases can be equalized as much as possible and in which the overall dimension of protrusion of the coil end parts in the winding coils of the three phases can be reduced to an optimal dimension is provided. Each of unipolar coils forming the winding coils of the three phases has a pair of coil end parts protruding from end parts in the axial direction of a stator core. The winding coils of the three phases have the relationships of Cv/Cu=0.88 to 0.98 and Cw/Cv=0.88 to 0.98, where Cu, Cv, Cw represent average lengths of electric wires forming the coil end parts in the three phases of U-phase, V-phase and W-phase.
