A rotor of the permanent magnet rotating electric machine includes a rotor core, a plurality of magnets, and magnetic slits. Each of the magnetic slits is formed in a core region being a region between magnets of the plurality of magnets, and a gap. The magnetic slits are regions having a lower magnetic permeability than a magnetic permeability of the core region. One end of each of the magnetic slits, which is closer to an outer periphery of the rotor, is positioned in a portion of the core region on the same direction side as a direction of a force in a circumferential direction of the rotor, and another end closer to the rotation axis center of the rotor is positioned on the magnetic pole center or in a portion of the core region on a side opposite to the direction of the force.
