PROBLEM TO BE SOLVED: To provide a rolling bearing remarkably excellent in wear resistance in a molten metal. SOLUTION: An inner ring 1A, outer ring 1B, and rolling elements 3 are formed of a silicon nitride or a sialon. A cage 2 is formed of a high purity two-dimensional C/C composite in which a pyrolytic carbon or vitreous carbon is charged between two-dimensionally woven carbon fibers, and the charged carbon is graphitized and treated to high purity, and contains ash content of 10 ppm or less.
