Abstract
An example motor rotor includes a cylindrical magnet which is disposed around a rotation shaft, a protective layer which is disposed around the magnet, and a middle resin portion which is disposed between the magnet and the protective layer. The magnet has a cylindrical shape that extends continuously in a circumferential direction of the rotation shaft. A surface treatment portion is formed on at least one of an outer peripheral surface of the magnet or an inner peripheral surface of the protective layer, to impart adhesion with the middle resin portion.
