The present invention provides a rolling bearing which can be large-sized, is excellent in its 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 (1) has an inner ring (2), an outer ring (3), and rolling elements (4) 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 (1) to be fixed. The film formed on the surface (c, d) thereof to be fixed is porous. The base material of the bearing members consists of an iron-based material. The film is a thermal sprayed film formed by using a material containing any of elements zinc, aluminum, and magnesium as a thermal spraying material. |
