The purpose of the present invention is to provide a rotor capable of high-speed rotation, high torque, andimproved assemblability, and a rotating electrical machine equipped with the rotor. A permanent magnet constituting one magnetic pole is configured from three magnet blocks (8a, 8b, 8c) arranged so as to be separated from each other in the circumferential direction. The three magnet blocks (8a, 8b, 8c) are formed such that the cross sections thereof orthogonal to the axial center of the rotary core (7) protrude in the radially outward direction, and such that the further away a magnet block is from the center of a magnetic pole (20), the narrower the circumferential width of that magnet block. The three circumferentially-arranged magnet blocks (8a, 8b, 8c) are configured mirror-symmetrically with respect to a plane passing through the center of the magnetic pole (20) and the axial center of the rotary core (7).
