Abstract: A ball bearing includes an inner ring; an outer ring placed outside of the inner ring; a plurality of rolling bodies intervening between the inner ring and the outer ring; and an annular cage including pockets rotatably holding the rolling bodies in a circumferential direction at intervals determining a rotation axis to be a center. The cage comprises a resin composition comprising a polyetherketone-based resin, graphite, and a carbon fiber. The resin composition comprises the polyetherketone-based resin in an amount of 60% by weight or more and 80% by weight or less, the graphite in an amount of 10% by weight or more and 30% by weight or less, and the carbon fiber in an amount of 5% by weight or more and 20% by weight or less when the entire resin composition is determined to be 100% by weight.
