Provided is a rolling bearing in which even when used in an environment in contact with a lubricating oil containing a sulfur-based additive, peeling of a film formed on the surface of a cage and elution of a metal component do not easily occur. A rolling bearing (1) comprising a plurality of rolling elements (3) and a cage (2) for holding the rolling elements (3) and used in an environment in contact with a lubricating oil containing a sulfur-based additive, A metal film that hardly peels off or dissolves under the environment is formed on the surface portion of the cage 2, and this metal film is a copper alloy film, particularly a copper-tin alloy plating film.
