According to the invention, there is provided a rotor for a rotating electrical machine which includes a rotary shaft, a pair of first and second pole cores fixed on the rotary shaft, a plurality of permanent magnets, and a magnet holder holding the permanent magnets. The magnet holder is made of a non-magnetic metal and has a plurality of holding portions and a plurality of connecting portions. Each of the holding portions is interposed between circumferentially adjacent two of claws of the first and second pole cores, so as to hold a corresponding one of the permanent magnets between the adjacent two claws. Each of the connecting portions circumferentially extends, through the radially inner side of a distal end portion of one of the claws of the first and second pole cores, to connect end portions of adjacent two of the holding portions which circumferentially bracket the distal end portion.
