Method for producing anodized structure

摘要

Disclosed is a method for producing a structure having: a stripping step in which an aluminum member including an aluminum substrate and an anodized layer present on the aluminum substrate, which layer contains micropores having an average pore diameter of 10 to 500 nm and a coefficient of variation in pore diameter of less than 30%, is electrolyzed in an aqueous acid solution by using the aluminum member for a cathode to thereby strip the anodized layer off the aluminum substrate so as to produce a structure composed of the anodized layer with a plurality of recesses. The method can produce a structure having regularly arranged recesses in a reduced time.
