    • PROBLEM TO BE SOLVED: To provide a method for forming a carbonaceous film which can realize an ultra-low friction surface having a frictional coefficient of 0.1 or less and having a practical area, by using fullerene as a raw material.
      SOLUTION: This forming method includes forming the carbonaceous film made from fullerene on a substrate by a cluster ion beam technique or a molecular beam epitaxy technique, by using fullerene as the raw material. The carbonaceous film formed on the substrate is typically made from fullerene C60. A highly oriented graphite (HOPG) is preferably used as the substrate for forming the film thereon.
