Zusammenfassung:	To provide a rotary electric machine in which a stator and a rotor can be efficiently cooled.SOLUTION: From a stator-side injection hole 107 and rotor-side injection holes 108, 110 formed in a liquid pass 100 that is for a cooling liquid CL and that is formed inside the bottom surface side of a motor cover 20, the cooling liquid CL is simultaneously injected toward a coil 34 of a stator 36 and an inner space of a bottomed cylindrical portion 30 of a rotary shaft 14 to which a rotor 44 is externally fitted. Inside the rotor 44, liquid passes 121, 122, 123, 116 that are connected with suction ports 111, 112, 113 formed in an inner surface of the bottomed cylindrical portion 30 and that are extended to discharge ports 131, 132 in end plates 48, 50, are formed.SELECTED DRAWING: Figure 2
