PROBLEM TO BE SOLVED: To provide a rolling bearing for suppressing the deterioration of a fretting abrasion resistant characteristic even reducing the quantity of lubricant to be enclosed, and moreover improving the fretting abrasion resistant characteristic. SOLUTION: A titanium oxide layer is formed onto at least one side of a rolling contact race surface and a rolling element surface, and is preferably to be an anatase-type having a coat thickness of 0.3-5.0μm. Consequently lubricating oil can be used as lubricant, and moreover a fretting abrasion resistant characteristic can be improved even reducing the lubricating oil into fine quantity.
