PROBLEM TO BE SOLVED: To provide a rolling bearing used favorable, particularly in a fuel injection control device of a car, having excellent low-temperature torque performance and high-temperature durability compared with any conventional arrangement and also an excellent low-temperature torque performance and high- temperature durability in the same manner even in a type of usage where the preload is large and the bearing pressure is high. SOLUTION: The rolling bearing is structured so that a grease is encapsulated therein whose base consists in perfluoropolyether oil having a straight chain structure with the 40°C dynamic viscosity ranging 20-100 mm<SP>2</SP>/s and which contains a thickening agent consisting of fluoro-resin particles and also at least one of such substances as ester series rust preventive agent, fluoride ether series diamide and fluoride ether series phosphoric acid.
