ABSTRACT:
An object of the present invention is to obtain an aluminum or aluminum alloy member having a uniform and dense anodic oxide film having sufficient corrosion and impact resistances. Provided is an anodic oxide film which has been formed on the surface of aluminum or aluminum alloy, the film comprising cells which have grown in random directions relative to the surface of the aluminum or aluminum alloy and thus have no orientation.
