PROBLEM TO BE SOLVED: To provide a rolling bearing excellent in rotating precision, which hardly produces unequal arrangement of rolling elements, and has an extremely little NRR-fc constituent. SOLUTION: This rolling bearing 1 comprises an inner ring 2; an outer ring 3; a plurality of balls 4 rotationally arranged between the inner ring 2 and the outer ring 3; and a crown retainer 5 for holing the balls 4 between both rings 2, 3. The crown retainer 5 is guided by the inner ring 2, and a guide clearance C is set to 0.25 to 1.5% of an inner diameter R of the bearing.
