Claim 9:
10. The rotating electric machine according to claim 9, wherein, when a point closest to the gap surface of a magnet insertion hole positioned at a head in the direction opposite to the direction of the circumferential force acting on the rotor when the stator coil is energized, in the magnet insertion hole into which the permanent magnet forming one magnetic pole is inserted, is represented by a point A,
an intersection closer to the point A of the two intersections between the cutout and the gap surface is represented by a point N,
an intersection closer to the point A of two intersections between the gap surface and an imaginary cutout obtained by imaginarily moving the cutout in the circumferential direction until the cutout is in contact with the slit is represented by a point B,
a rotation center of the rotor core is represented by a point O,
an angle between a straight line OA connecting between the point A and the point O and a straight line ON connecting between the point N and the point O is represented by θ, and
an angle between the straight line OA connecting between the point A and the point O and a straight line OB connecting between the point B and the point O is represented by Φ,
θ/Φ satisfies 0<θ/Φ<0.47.
