Summary:PROBLEM TO BE SOLVED: To provide a rolling bearing considerably improved in terms of low torque, low noise and a long service life than before and sufficiently coping with high temperature and high speed rotation. SOLUTION: The rolling bearing 1 is constituted by holding a plurality of rolling elements 13 between an inner ring 10 and an outer ring 11 through a cage 12 and filled with grease containing a metallic detergent-dispersant of calcium sulfonate, barium sulfonate or calcium salicylate, and an ashless detergent-dispersant of a succinate derivative or benzylamine in total at a rate of 0.5-10 wt.% of the total amount of grease, wherein dynamic viscosity at 40°C of base oil is 60 mm2/s or less.
