A rolling bearing includes an inner ring, an outer ring, a plurality of balls, a cage that holds the balls, and a sealing device that is attached to each of opposite sides of the outer ring in an axial direction to prevent foreign matter from entering inside the bearing. A noise-reduction portion that attenuates sound inside the bearing is formed on at least one of a surface of the cage and a bearing inner-side surface of the sealing device.
