PROBLEM TO BE SOLVED: To provide a metal surface structure which avoids defects relating to hardness such as thermal softening property of a fluororesin layer and which has remarkably improved workability as compared with the conventional formation of a fluororesin layer. I do. A hard inorganic layer containing fine particles of inorganic oxide, which is provided so as to cover at least the surface of the metal material, and is provided so as to cover the surface of the hard inorganic layer. A metal surface structure with a non-stick ceramic layer. |
