PROBLEM TO BE SOLVED: To provide a cooling structure of a motor for quickly dissipating heat without increasing a Joule heat or the like even when a stator is operated at high speed rotation, by molding a stator and by quickly dissipating heat and efficiently cooling the stator. SOLUTION: The cooling structure of the motor includes: a case 5 covering an inside of the motor formed with a molded stator 3 and a rotor 2 which pairs with the stator 3; and a cover 7 fitted with the case 5. The cooling structure of a motor interposes a spring member being as a thermally conductive member 9 which is constituted to dissipate heat by that a contact area of the stator 3 is enlarged by a thermal expansion which occurs when the stator 3 is heated, and to separate the stator 3, the case 5 and the cover 7 when the stator 3 is not heated.
