Disclosed is a method for forming an anodized layer, said method including: a step (a) that prepares an aluminum substrate (18) having a machined surface (18s); a step (b) that forms micro-asperities on the surface of the aluminum substrate such that the mean distance between adjacent concavities is less than the mean distance between adjacent microscopic concavities (12) in a porous alumina layer which is the goal; and a step (c) that anodizes the surface of the aluminum substrate (18) after step b, thereby forming a porous alumina layer (10) having a plurality of microscopic concavities (12). Via this method, a porous alumina layer can be formed on a machined surface of an aluminum substrate, said porous alumina layer having an even distribution of microscopic concavities.
