Abstract:
A method for manufacturing a mold includes (a) anodizing an aluminum substrate at a voltage of 60 V to 120 V in an electrolytic solution in which two or more species of acid are mixed, and forming an oxide film having a plurality of minute holes on a surface of the aluminum substrate; and (b) removing at least a portion of the oxide film. The electrolytic solution used in (a) satisfies the relation (D1)/2
