A rotor includes magnets, and magnet holes each of which includes an opening extending in a radial direction in plan view, penetrates a rotor core in the axial direction, and includes the magnet located therein. A magnetic pole surface of the magnet opposes a circumferential direction. The rotor core includes first thin plate cores and second thin plate cores. The first thin plate cores include an annular first inner plate, first outer plates on a radially outer side of the first inner plate and arrayed side by side in the circumferential direction, first inner connecting portions connecting the first inner plate and the first outer plate, and a first outer connecting portion that is on a radially outer side of the first outer plate and connects the adjacent first outer plates in the circumferential direction.
