<p>The method for producing an anodized film of the present invention includes a step (a) a for preparing a laminated structure (10) that comprises a substrate (12), a sacrificial layer (16) containing aluminum formed on the substrate (12), and an aluminum layer (18) formed on the surface of the sacrificial layer (16); a step (b) for forming a porous alumina layer (20a) having multiple fine indentations (22a) by partial anodization of the aluminum layer (18); and a step (c) for separating the porous alumina layer (20a) from the laminated structure after the step (b). By means of this invention, it is possible to produce, more easily than in the past, a self-supporting anodized film having a porous alumina layer.</p> |
