Abstract
A diamond thin film coating method is provided that enables, with no need for an intermediate layer, the formation of a diamond thin film, which has conventionally been considered difficult because cobalt contained in a binding phase of a cemented carbide provides a catalysis for the formation of graphite.), and thereafter the diamond thin film is formed.
