PROBLEM TO BE SOLVED: To prolong the life of a rolling bearing in an environment such as in a vacuum, a high temperature, corrosive gas, liquid, or molten metal in which an ordinary lubricant such as oil or grease cannot be used by improving the shift adhesiveness of a 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 made of silicon nitride ceramic, and a retainer 5 made of polytetrafluoroethylene, and the surface roughness of the raceway surface of each outer ring 2 and inner ring 3 is set in a range of 0.1μmRa-3.2μmRa.
