Patent ID: 8691364

Claim:
A laminate comprising a substrate; a carbon layer; and an adhesiveness-reinforcing layer provided between the substrate and the carbon layer, the adhesiveness-reinforcing layer comprising a diamond fine grain which is crushed by impact given thereto, wherein the diamond fine grain adheres to or anchors cutting into a surface of the adhesiveness-reinforcing layer, wherein the substrate comprises any one of iron, iron-base alloy, stainless, aluminium, copper and plastic, the adhesiveness-reinforcing layer comprises any one of titanium, titanium nitride, silicon carbide and silicon nitride, the carbon layer comprises a carbon grain; and a formation/growth inhibiting material that inhibits the formation of an impurity inhibiting the growth of the carbon grain and/or inhibits the growth of the carbon grain, an amount of the formation/growth inhibiting material decreases from a lower layer toward an upper layer on the adhesiveness-reinforcing layer side, and the carbon layer includes 70 atomic % or more of the carbon grain in 80 nm or more from an upper surface of the adhesiveness-reinforcing layer side.
