A rotor adapted for a large permanent magnet rotating machine having high output and demagnetization resistance and the permanent magnet rotating machine are provided. More specifically, there is provided a rotor adapted for a permanent magnet rotating machine, the machine comprising the rotor and a stator disposed with a clearance from an outer peripheral face of the rotor and formed by winding a winding wire through a stator core having two or more slots, the rotor comprising one or more permanent magnets in each of two or more insertion holes, the insertion holes being formed in a circumferential direction in a rotor core, wherein a magnetic coercive force in a stator-side surface region of each of the permanent magnets is greater than that in an inner central portion by 300 kA/m or more, the inner central portion being an inner portion at a depth of at least 5 mm from every outer shape face of the permanent magnet. There is also provided the permanent magnet rotating machine comprising this rotor and a stator disposed with a clearance from an outer peripheral face of the rotor and formed by winding a winding wire through a stator core having two or more slots.
