PROBLEM TO BE SOLVED: To provide a highly reliable rolling bearing having a cage which maintains heat resistance and chemical resistance inherent to a polyphenylene sulfide resin and furthermore has improved mechanical strength and also sufficient resistance to high-temperature gear oil. ! SOLUTION: A cage 14 of a rolling bearing 10 including at least, an inner ring 12, an outer ring 11, the cage 14 and rolling elements 13 is formed of a resin composition which is obtained by mixing the polyphenylene sulfide resin with at least carbon fibers and 0.1-30 mass% of nano-filler based on the whole resin composition. !
