A rotor of a rotary electric machine includes a rotor shaft, a rotor core fixedly supported on an outer circumference of the rotor shaft. The rotor shaft is provided, in a cross section perpendicular to the rotation axis, with a first outer edge portion projecting in a radial direction of the rotor shaft, and a second outer edge portion arranged in line with the first outer edge portion one after the other in a circumferential direction of the rotor shaft. The rotor core has a core insertion hole into which the rotor shaft is inserted, and a shaft holding portion on an inner circumference forming the core insertion hole, the shaft holding portion being configured to hold the first outer edge portion from the opposite sides in the circumferential direction of the rotor shaft. The shaft holding portion is in a non-contact state with the second outer edge portion.
