PROBLEM TO BE SOLVED: To provide an inexpensive rotor for a rotary electric machine, which fully exhibits magnetic characteristics and enables fixation of a magnet by simple manufacturing process without using an adhesive agent. SOLUTION: The rotor for the rotary electric machine includes laminated cores 1 having a penetration hole 2 at the center portion allowing a shaft 3 to pass therethrough, and a plurality of substantially circular arc-shaped magnets 5 are arranged on the outer circumferential portion of the laminated cores 1. The laminated cores 1 are constituted by laminating a large number of substantially disk-like steel plates 11 having the shaft insertion hole 12 formed at the center portion thereof. The laminated cores includes, inside of the respective steel plates 11, a projection part forming steel plate 11, located between the mutually adjacent magnets 5, wherein the claw-shaped projecting part 13 abutting on the magnets 5 on both sides is formed only in one portion of the outer circumferential portion, allowing the projection forming steel plate 11 to be provided in any layer so as to interpose the claw-shaped projection part 13 between the mutually adjacent magnets 5 in at least one portion.
