To provide a ball bearing capable of suppressing inflow of lubricant to an outer ring raceway surface to reduce stirring resistance, torque and heat generation, even in a case where the lubricant is scattered due to centrifugal force in high-speed rotation.SOLUTION: In a ball bearing 1, a radial wall thickness T of a crown type holder 10 gradually becomes thinner from a base part 11 to the tip of a claw part 14. Further, a radial gap a between the outer peripheral surface of the base part 11 of the crown type holder 10 and the inner peripheral surface of a shoulder part 8 of an outer ring 3 is larger than a radial gap b between the inner peripheral surface of the base part 11 and the outer peripheral surface of a shoulder part 9 of an inner ring.SELECTED DRAWING: Figure 1
