PROBLEM TO BE SOLVED: To further extend the life of a rolling bearing which is excellent in electrolytic corrosion prevention effect and uses a rolling element made from silicon nitride.SOLUTION: The rolling bearing includes an inner ring, an outer ring, a rolling element, and a holder. The rolling element is made from silicon nitride being made dense by a filtering aid. The maximum diameter of segregation substances of the sintering aid on the surface is 20 μm or less. The thickness of a remaining sintering effect layer is 1.0% or less relative to the radius of the rolling element. |
