摘要： A cooling structure of a rotor for a rotary electric machine includes: a rotatable shaft that is configured to supply coolant that flows inside the shaft to outside the shaft; a rotor core that is fitted onto the shaft and fixed thereto, and has a coolant flow path for flowing the coolant, in an axial direction of the rotary electric machine, that is supplied from the shaft, and is formed of a plurality of magnetic plates stacked together in the axial direction of the rotary electric machine; and a coolant impermeable nonmagnetic member that is provided in the rotor core near an inner circumferential surface on a radially outer side in a radial direction of the rotor core, of the inner circumferential surface of the coolant flow path.
