Claim:
1. A rotating electric machine comprising: a stator including a coil and a stator core; and a rotor opposed to the stator with a gap intervening between the rotor and the stator, the rotor including permanent magnets and a rotor core, the rotor being configured such that the permanent magnets are buried in V-shape at hole-shaped slots disposed in the rotor core to form one pole, the pole being formed in plurality in a circumferential direction, wherein: each of the slots is an open slot partially opened toward an outer circumference of the rotor core; the slot is provided with a hook-shaped structure to support corresponding one of the permanent magnets in an open portion thereof; and the slot includes a protrusion so that on a section perpendicular to an axial direction of the rotor, the permanent magnet comes into contact with the rotor core at a position closer to an inner diameter side of the rotor than to a midpoint on an outer diameter long side of the permanent magnet.
