A rotor includes a rotor core, including a magnet accommodation cavity, and a permanent magnet, embedded in the magnet accommodation cavity of the rotor core and including a bent portion located toward a radially inner side of the rotor core. The permanent magnet has a thickness to satisfy an expression of 0.0006D+0.1626−0.5/(D/2)≤Wm/(D/2)≤−0.0006D+0.1626+0.5/(D/2).
