Provided is a rotary electric machine, including: a stator; and a rotor provided on the stator so as to be rotatable about a rotation shaft, in which the rotor includes, at an outer circumference thereof, magnetic poles arranged so as to have different polarities alternately, the magnetic poles being formed of a rotor core in which electromagnetic steel plates are stacked, the magnetic poles being excited by permanent magnets which are housed in gaps disposed at an outer circumferential part of the rotor core, and in which the rotor core includes, at an inner circumferential part thereof, in the same stack plane: a short circuit magnetic path connecting magnetic pole pieces which form the magnetic poles; and a protruding portion held in contact with the permanent magnets, which is positioned between magnetic pole pieces which are not connected to the short circuit magnetic path.
