PROBLEM TO BE SOLVED: To provide a rolling bearing improved in reliability by comprising a cage improved in oil-resistance in a high-temperature environment and improved in strength, maintaining heat resistance and chemical resistance particular to a polyphenylene sulfide resin. SOLUTION: In a bearing comprising at least an inner ring, an outer ring, a cage and a rolling body, the cage is formed from a polyphenylene sulfide resin composition containing a toughening agent, which is composed of an ethylene group copolymer containing glycidyl methacrylate of 3-20 mole% in molecule structure, of 5-20 mass% in relation to the whole quantity and a reinforcing fiber material of 10-40 mass% in relation to the whole quantity.
