A rolling bearing including a rolling bearing ring and a rolling element, at least one of the rolling bearing ring and the rolling element consisting of carburized steel containing at least 0.3% and at most 0.6% of C, at least 0.1% and at most 0.35% of Si, at least 1.1% and at most 1.5% of Mn, at least 0.5% and at most 2.0% of Cr, at least 0.2% and at most 0.6% of Ni and at least 0.15% and at most 0.5% of Mo by weight. Thus, an inexpensive and long life carburized steel rolling bearing can be obtained using a combination of chemical components of a relatively low cost.
