PROBLEM TO BE SOLVED: To provide a structure inexpensive equivalent to non-magnetic stainless steel and with high non-magnetic action as compared with the non-magnetic stainless steel, though harmless, in a rolling bearing. SOLUTION: At least one of races 2, 3 or a rolling unit 4 is formed by an Mn-Ni-Cu system alloy. This Mn-Ni-Cu system alloy is equivalent to non- magnetic stainless steel without containing a harmful component relating to the human body, and can be much inexpensively manufactured as compared with ceramics, and relative magnetic permeability is nearer to 1 than that of the non-magnetic stainless steel.
