A corrosion-resistant structure of a metal material, characterized in that it comprises a metal material and, formed thereon, a coating layer comprising titanium oxide and an electroconductive metal oxide. In a preferred embodiment, said electroconductive metal oxide is an Sn oxide. A method for treating a surface of a metal material, wherein the surface of the metal material is coated with an SnOx . TiO2 sol and then is fired, for example, at 150ringC, to form a corrosion-resistant structure. The corrosion-resistant structure can be formed through a firing at a relatively low temperature, and has advantageous corrosion-resistance effect, and further exhibits the persistence of the corrosion-resistance effect even after a light is cut off.
