PROBLEM TO BE SOLVED: To provide a minor diameter rolling bearing inside diameter of of 10mm or less capable of performing a stable rotation in a wide range of temperatures from low temperatures to high temperatures with reduced starting and rotating torques at low temperature. SOLUTION: This rolling baring of 10mm or less in inside diameter comprises a plurality of rollers retained between an inner ring and an outer ring through a retainer so as to be capable of rolling. A grease obtained by mixing at least one selected from urea compound, lithium soap and lithium composite soap as a thickener to a base oil having a kinetic viscosity at 40°C of 15mm<SP>2</SP>/s and containing an ester oil as an essential component is sealed in this bearing.
