PROBLEM TO BE SOLVED: To provide a cooling structure of a rotary electric machine capable of completely preventing leakage of refrigerant, without having to increase the thickness of a resin layer. SOLUTION: This rotary electric machine is constructed so as to store a coil 13 concentratedly wound around each teeth portion 11 of a stator 10 in a slot 12 between the teeth portions 11. In the internal space of the slot 12, a plurality of pipes 15 extending axially are disposed so as to be parallel to each other. A resin layer 17, for closing a slot opening by charging resin material, is formed in a clearance in between the pipes 15 and a clearance between the pipe 15 and a coil 13, and a refrigerant is made to flow through the inside of the pipe to cool the stator 10.
