Method for producing a substrate comprising a metal body

Excellent film-forming characteristics (reflectance and adhesiveness), it is easy to apply to larger substrates, yet can be implemented at low cost, to provide a method of manufacturing a substrate comprising a metal body. The (A) complexes generating a steam heated to the complex to a first temperature, contacting the substrate heated to the second temperature is (B) wherein said vapor first temperature below , at least a portion alone or the compound of the central metal of the complex (excluding. the complex) and forming a metal member including a method of manufacturing a substrate comprising a metal body surface of the substrate. Second temperature of step (B) is less than the decomposition temperature of the complex. Central metal of the complex is aluminum or titanium.
