A flux barrier includes a radially outer proximate part and a radially inner proximate part that are a rotor radially outer side surface and a rotor radially inner side surface extending from a communicating part, at least one of the radially outer proximate part and the radially inner proximate part is connected to an end part of a magnet fixing part of a magnet hole in an inward direction of the magnet hole, and a projecting part projecting in an inward direction of the flux barrier is provided on at least one of the radially outer proximate part and the radially inner proximate part connected to the magnet fixing part. A constricted part in which a width of the flux barrier is narrower than on a side closer to the communicating part than the projecting part is formed by the projecting part.
