Abstract
A composite material comprising a substrate and a single or multiple surface layer formed thereon is disclosed. The surface layer has a structure in which the side in contact with the substrate contains a comparatively large amount of an adhesive component which bonds the surface layer to the substrate and the side opposite to the substrate contains a comparatively large amount of a protective component having characteristic chemical and physical properties. The amounts of the two components vary continuously across the thickness of the surface layer. The surface layer is formed by plasma polymerization.
