PROBLEM TO BE SOLVED: To provide the rotor of a rotary electric machine through which demagnetization of a permanent magnet is avoided and high temperature operation is realized. SOLUTION: The rotor of a rotary electric machine comprises a disc-like rotor core 11, a plurality of permanent magnets 13 and 14 arranged on the rotor core 11 along the circumferential direction while changing the polarity alternately, and a plurality of first slits 15 formed in the rotor core 11 substantially in parallel with the flux of each permanent magnet 13, 14 while spaced apart from each other. Each permanent magnet 13, 14 has IPM (Interior Permanent Magnet) structure buried in the rotor core 11 and the plurality of first slits 15 are provided only on the outer circumferential side of each permanent magnet 13, 14.
