PROBLEM TO BE SOLVED: To prolong the life of a rolling bearing under the environment such as in vacuum, high temperature, corrosive gas, liquid, or molten metal in which ordinary lubricant such as oil or grease can not be used by improving shift adhesiveness of solid lubricant from a self-lubricating retainer. SOLUTION: This rolling bearing is constituted of an outer ring 2, an inner ring 3, and rolling bodies 4 respectively made of silicon nitride ceramics, and a retainer 5 made of polytetrafluoroethylene, and the surface roughness of the respective raceway surfaces of the outer ring 2 and the inner ring 3 are set in the range of 0.1μmRa-3.2μmRa.
