20110143976	NITROGEN-CONTAINING AMORPHOUS CARBON-TYPE FILM, AMORPHOUS CARBON-TYPE LAMINATION FILM, AND SLIDING MEMBER - Provided is a nitrogen-containing amorphous carbon film exhibiting excellent durability even when formed on the surface of a sliding member used under high surface pressure or under a lubricating oil environment. The nitrogen-containing amorphous carbon film is formed by physical evaporation onto the sliding surface of a sliding member and contains 8.0 to 12.0 atomic % of hydrogen and 3.0 to 14.0 atomic % of nitrogen. The nitrogen-containing amorphous carbon film is effective when, for instance, formed on at least one sliding surface of a sliding member, such as a sliding part of an automobile engine.	06-16-2011
