The present invention relates to a coil cooling device of a motor which comprises: a cooling cap part covering a winding end of a stator coil bundle and coupled to the stator, wherein the cooling cap part has a flow path, through which a fluid can flow, formed therein; an inflow passage part formed on one side of the cooling cap part and configured to form an inflow path through which a fluid flows into the cooling cap part; a discharge flow path part formed on the other side of the cooling cap part and configured to form a discharge path through which a fluid is discharged to the outside of the cooling cap part; and a cap fixing part for fixing the cooling cap part to the stator or a motor housing. Therefore, the coil cooling device of the motor directly and uniformly cools the stator coil of the motor to achieve a high output of a motor for driving a vehicle.
