A rotary electric machine includes a stator and a rotor located in a rotatable manner relative to the stator via a gap. The stator includes a multi-phase stator winding that is held in a plurality of slots formed in the stator. The rotor includes at least one magnet section embedded therein so as to face the slots. The magnet section includes a plurality of axially laminated magnets with a skew angle which is an angle of a positional difference between the magnets. This skew angle thetas is set so as to satisfy thetas=kalpha/2 where alpha is a slot pitch which is an angle between the slots, and k is a coefficient set based on: an arc ratio thetaa being an angle covering an area in which magnetic flux radially flows from the magnetic section; and a slot factor S being a ratio of the slots relative to the magnet section.
