A permanent magnet rotating electric machine includes a stator and a rotor disposed with an air gap interposed between the stator and the rotor. The rotor is provided with a rotor core provided with a plurality of magnet insertion holes in a circumferential direction, and a press-fit body pressed into each of the magnet insertion holes. The press-fit body includes a permanent magnet and a magnet fixing member provided on the sides of the permanent magnet. The press-fit body is fixed within the magnet insertion hole in such a way that, in the circumferential direction, one end of the press-fit body makes a line contact with the inner wall of the magnet insertion hole through a line contact portion of the magnet fixing member and the other end thereof makes a surface contact with the inner wall of the magnet insertion holes through a surface contact portion of the magnet fixing member.
