Claim 8:
9. A rotating electric machine in which a rotor provided inside a stator in a radial direction of the stator is to be rotated, the rotating electric machine comprising:
a pair of permanent magnets arranged in the rotor separately in a circumferential direction:
a first magnetic slit which is provided inside the pair of permanent magnets in the circumferential direction, and has an arc shape in which an intermediate portion protrudes from both end portions inwardly in the radial direction; and
a second magnetic slit which is provided inside the pair of permanent magnets in the circumferential direction and closer to the pair of permanent magnets side in the circumferential direction than the first magnetic slit is provided, and has an arc shape which is split into a plurality of portions and in which an intermediate portion protrudes from both end portions inwardly in the radial direction,
wherein the first magnetic slit is formed of a non-magnetic region continuous in a longitudinal direction in a protruding portion protruding in an arc shape, and
wherein the plurality of portions included in the second magnetic slit are arranged along a radial direction of the rotor core so as to be spaced apart from each other, and are arranged separately in the radial direction so as to be spaced apart from each other in a protruding portion which protrudes in the arc shape in the second magnetic slit, the protruding portion functioning as a magnet magnetic flux guide path.
