PROBLEM TO BE SOLVED: To provide a rotor of a rotary electric machine capable of preventing breakdown or deformation of a magnetic pole by raising strength of the magnetic pole while reducing the whistling of wind, and capable of suppressing increase in a magnetic resistance caused by the air layer inside an iron core. SOLUTION: The rotor is composed of first and second cylindrical magnetic poles 33 and 34 of which a cylindrical magnetic pole part of a rotor core 20 is a mass body. First and second tab-like magnetic poles 24 and 25 are separated from each other at the inner peripheral side by first and second grooves provided on the inner peripheral surfaces of the first and second cylindrical magnetic poles 33 and 34, while connected to each other at the outer peripheral side by first and second thin skins 37 and 47 composed of the bottom parts of the first and second grooves, for arrangement in circumferential direction.
