Abstract

Disclosed is a method for forming a protective film having high corrosion resistance. The method comprises bringing warm water (46) having a temperature of 70°C or above and 90°C or below (first temperature) into contact with an anode oxide film (12) to form a discontinuous face on the surface of the anode oxide film (12) and then bringing hot water having a second temperature, which is above the first temperature, or a water vapor having the second temperature into contact with the film. The hot water or the water vapor is introduced through the surface of the anode oxide film (12) into the inside of the anode oxide film (12). Accordingly, voids on the surface portion in the anode oxide film (12) are clogged by a hydrate formed upon the contact of the voids with the hot water or the water vapor. Therefore, a protective film formed of a dense layer can be reliably formed on the surface of the anode oxide film (12).
