PROBLEM TO BE SOLVED: To materialize durable water repellency as a material for a metal product by forming a water-oil repellent coat of a hydrophobic resin containing fine powder on the surface of a metallic material having fine uneven structure on the surface. SOLUTION: The surface roughness of a metallic material is regulated to be 0.1-50μm by an etching process, and on the metal surface, a water-oil repellent coat consisting of a resin having trifluoromethyl groups which contains fine powder or the mixture of the resin and a general purpose resin is formed. By forming the coat, fine powder is stuck on a flat part which had existed on the metal surface to form new fine uneven structure. In this way, durable water repellency can be materialized as a material for a metal product to accomplish the prevention of adhesion of water, frost, snow, ice, etc.
