1. A stator coil comprising a coil group of three-phase coils of a U-phase, a V-phase and a W-phase mounted in a circumferential direction of a stator core, each including a plurality of straight portions extending in an axial direction of the stator core and into slots of the stator core, the three-phase coils each including an input terminal at one end in an extension direction of the three-phase coils and a midpoint terminal at an other end
wherein the coil group is folded back in the circumferential direction of the stator coil at a folded-back portion arranged in a middle so that the input terminal and the midpoint terminal of each of the three-phase coils are arranged together at an opposite end of the stator core in the circumferential direction with respect to the folded-back portion in the coil group resulting in forward portions and backward portions of the plurality of straight portions being laminated in a radial direction of the stator core,
the input terminals and the midpoint terminals of the respective three-phase coils are alternately arranged in the circumferential direction of the stator core.
