ROTOR

A rotor that includes a rotor core having a plurality of electrical steel sheets stacked in an axial direction; and a permanent magnet embedded in the rotor core and disposed so as to face a stator, wherein: the electrical steel sheet has, in each magnetic pole: a plurality of holes including at least a magnet insertion hole in which the permanent magnet is inserted, a stator-side bridge that is a bridge between one of the holes and a stator opposing surface of the rotor core, an inter-hole bridge that is a bridge between two of the holes which are adjacent to each other in a circumferential direction, and a non-bridge n that is a portion other than the stator-side bridge and the inter-hole bridge.
