PROBLEM TO BE SOLVED: To provide a rotor having a rotor core reduced in weight without causing a rise in magnetic resistance while ensuring a magnetic path, and to provide a rotary electric machine. SOLUTION: The rotor 20 has a rotor core, salient pole portions 132A, 132B formed on the circumferential surface of the rotor core and protruding toward the outside of the diameter direction, and openings 133A, 133B having tapered openings 134A, 134B positioned in the inside of the diameter direction for the salient pole portions 132A, 132B and tapered to the outside of the diameter direction of the rotor core.
