Abstract
A rotary electric machine that includes a rotor; and a permanent magnet, wherein: in an axially orthogonal section orthogonal to a rotational axis of the rotor in an attached state in which the permanent magnet is attached to the rotor, the permanent magnet has an uneven shape, in which both of two magnetic pole surfaces are repeatedly projected and recessed with a curvature that is larger than an average curvature of magnetic pole surfaces.

- a permanent magnet, wherein:
- in an axially orthogonal section orthogonal to a rotational axis of the rotor in an attached state in which the permanent magnet is attached to the rotor, the permanent magnet has an uneven shape, in which a virtual central line is repeatedly projected and recessed with a curvature that is larger than an average curvature of two magnetic pole surfaces, the virtual central line connecting intermediate positions of a separation distance of magnetic pole surfaces.
