The invention provides a rotor and a motor that facilitate the adjustment of the magnetic flux while keeping the number of components low. The rotor includes first and second rotor cores, a disk magnet, and a rectifying magnet. The first and second rotor cores each include a core base and claw-poles. The disk magnet is magnetized in the axial direction so that the claw-poles of the first rotor core function as first poles and the claw-poles of the second rotor core function as second poles. The rectifying magnet includes at least an inter-pole magnet portion or a back-surface magnet portion. The inter-pole magnet portion is located in a gap formed in the circumferential direction between the claw-poles of the first rotor core and the claw-poles of the second rotor core. The back surface magnet portion is located in a gap formed at back surfaces of the claw-poles. The rectifying magnet and the disk magnet are formed from different materials. The rectifying magnet is integrated with the disk magnet in a post-process.
