Abstract:
A metal oxide film suitable for protection of metals, composed mainly of aluminum. A metal oxide film includes a film of an oxide of a metal composed mainly of aluminum, having a thickness of 10 nm or greater, and exhibiting a moisture release rate from the film of 1E18 mol./cm2 or less. Further, there is provided a process for producing a metal oxide film, wherein a metal composed mainly of aluminum is subjected to anodic oxidation in a chemical solution of 4 to 10 pH value so as to obtain a metal oxide film.
