Abstract
At least one of constituent elements of a rolling bearing is formed of a metallic material which contains an alloy element having a strong affinity for nitrogen while being of low grade in terms of cost and characteristics, and has a nitriding layer formed on surfaces thereof to be hardened. Accordingly, it is possible to use such rolling bearing as a substitute for conventional rolling bearings or rolling bearings of high grade which are known as general rolling bearings.
