Abstract
A rolling bearing which can be large-sized, has corrosion resistance, and is allowed to prevent mounting accuracy from deteriorating, a fixing force from decreasing, vibration from occurring at a portion of the rolling bearing to be fixed to a bearing box or the like, and can be used for a long term even in a highly corrosive environment. A rolling bearing () has an inner ring (), an outer ring (), and rolling elements () as bearing members thereof. Of regions of the bearing members which are exposed to a corrosive environment, a film having a sacrificial anode action for a base material of the bearing members is formed in a region including at least a surface (c, d) of the rolling bearing () to be fixed. The film formed on the surface (c, d) thereof to be fixed is porous.
