A motor rotor includes an inner sleeve, a cylindrical permanent magnet disposed around the inner sleeve, and a resin portion formed by charging a gap between the inner sleeve and the permanent magnet with a resin. The inner sleeve includes a small diameter portion. The small diameter portion is located to face an inner peripheral surface of an end portion of the permanent magnet in an axial direction. The small diameter portion is formed to have a diameter smaller than a diameter of a portion facing an inner peripheral surface of a center portion of the permanent magnet in the axial direction.
