PROBLEM TO BE SOLVED: To provide a relatively low-priced rolling bearing provided with a high-temperature service life, rust resistance and the low-temperature flowing ability. SOLUTION: In the rolling bearing 1 formed by holding a plurality of rolling bodies 13 between an inner ring 10 and an outer ring 11 and sealing the grease, as the grease, a grease composition obtained by mixing at least one of a metal complex soap group grease and an urea group grease respectively containing 8 to 35 % by mass of thickener and a fluoride group grease-containing perfluoropolyether oil as a base oil and 15 to 42.5 % by mass of polytetrafluoroethylene as the thickener at a following rate of mass ratio, at least one of the metal complex soap group grease and the urea group grease:the fluoride group grease=40-80:60-20, and containing the thickener of 20-30 % by mass in total is used.
