PROBLEM TO BE SOLVED: To provide a highly efficient permanent magnet rotating electric machine for reducing an influence of an iron loss and an electric vehicle using the permanent magnet rotating electric machine. SOLUTION: The permanent magnet rotating electric machine 1 includes a stator 2 in which a stator winding 5 is wound on a stator iron core and a permanent magnet rotor 3. A plurality of permanent magnets 6 whose polarities are arranged alternately in the circumferential direction inside the rotor iron-core 7, are inserted in the permanent magnet rotor 3. The permanent magnet rotor iron-core 7 has a magnetic pole piece 72, an auxiliary magnetic pole 71 and a stator yoke 74, and further has a recess part 76 provided in an air gap surface of the magnetic pole piece 72 of the rotor iron core 7 of the permanent magnet and smoothly inclined from the center of the magnetic pole to the end.
