PROBLEM TO BE SOLVED: To provide a rotor wherein magnet flux can be enhanced and further a permanent magnet can be installed with certainty. SOLUTION: In the rotor 10, a rotating shaft 14 penetrates a rotor core 12 in the center, and roofing tile-shaped permanent magnets 22 are embedded in multiple insertion holes 20, provided around the center of the rotor core in the axial direction. The roofing tile-shaped permanent magnets 22 are disposed, with their convex portions facing toward the rotating shaft, and the curvature of the convex portions is set to be smaller than the curvature of the concave portions of the permanent magnets.
