PROBLEM TO BE SOLVED: To provide a method for manufacturing a coating with catalytic action for synthesis of hydrogen cyanide on a molding. SOLUTION: In a method for manufacturing a coating with catalytic action, a molding is uniformly moistened with a coating dispersion liquid containing at least, one type of particulate platinum group element and any other coating component in a carrier liquid. In addition, the carrier liquid is evaporated and the coating is gradually heated at 1000-1350 deg.C in the presence of nitrogen and/or ammonium, so that the coating is shifted to a catalytic action effective state. In this case, a particulate nitride which has an average particle diameter considerably less than 100μm and contains elements such as aluminum, boron, titanium and silicon is used alone or in mixture form as another cationic coating component.
