A cooling structure of a rotary electric machine () that includes a rotating shaft (), a rotor (), and a stator () that includes a coil end (), includes a coolant passage () that is included in the rotating shaft () and through which coolant flows, and a squirt hole () that is included in the coolant passage (). The squirt hole () is included in the coolant passage (). An opening portion of the squirt hole () is positioned on an outer peripheral surface of the rotating shaft () and to an outside of the coil end () in the axial direction. The squirt hole () squirts the coolant such that the coolant is distributed to an inner peripheral surface (C, C) of the coil end () and an end surface (A, A) of the coil end () in the axial direction.
