The mold coating agent contains at least one of transition metal elements having a metal having an electron orbit d 3 to d 10 , an oxide of the metal, and a mixture containing the metal. For example, chromium (Cr), molybdenum (Mo), Tungsten (W), manganese (Mn), iron (Fe), Cobalt (Co), nickel (Ni), platinum (Pt), Palladium (Pd), silver (Ag), gold (Au), copper (C It can contain at least one of u). |
