Surface modification metallic member using the fluorine-containing silane coupling agent

The organic layer C is bound to 6 or more linear is formed on the corrosion-resistant metal. The method as a method of (1) both ends is reacted with a silane coupling agent of alkoxy groups to the metal, is reacted with an organic substance and a metal having a OH group, group capable of adsorbing to the metal on the opposite ends (2) one end method, (3) one terminal OH groups, a method of reacting a metal compound having a COO group capable of adsorbing to the metal on the opposite end, (4) one terminal alkoxy group, group capable of adsorbing to the metal to the inverted terminal a method of reacting a metal silane coupling agent having a. As to form a fluorine-containing silane coupling layer on. The number of carbon atoms of straight-chain 6 or more to form a silane coupling layer of fluorine-containing on the intermediate layer made of organic material (continuous or discontinuous), to prevent corrosion of the metal.
