A rotor includes a shaft extending in an axial direction, a rotor core including laminations stacked in the axial direction, and at least one caulking portion at a radial-directional inner side of at least one magnet to caulk the laminations to each other. At least one magnet is embedded in the rotor core. At least one fixing portion fixes at least portions of outer peripheral edges of the laminations to each other. The caulking portion, the at least one magnet, and the at least one fixing portion are all arranged to be intersected by a straight line which is on a flat two-dimensional plane extending in a radial direction and a circumferential direction.
