PROBLEM TO BE SOLVED: To provide a rolling bearing significantly excellent in wear resistance in molten metal. SOLUTION: An inner ring and an outer ring are formed of a composite material containing TiC-TiN or WC-TiC as a hard phase, and Ni-Cr or Ni-Cr-Co as a binder phase, and are structured such that a coating formed of any of TiC, TiN and Ti(C, N) is formed on each surface thereof by a CVD method (Chemical Vapor Deposition method). A rolling element thereof is made of silicon nitride. COPYRIGHT: (C)2008,JPO&INPIT
