摘要：
This method for producing anodic porous alumina such that an oxide coating film having a plurality of minute pores is formed at the surface of an aluminum substrate is characterized by containing: a step (a) for immersing the aluminum substrate in an electrolytic liquid resulting from mixing a plurality of acids; a step (b) for imposing a voltage on the aluminum substrate immersed in the electrolytic liquid; a step (c) for holding the aluminum substrate in the state of being immersed in the electrolytic liquid essentially without imposing a voltage on the aluminum substrate; and a step (d) for alternately repeating step (b) and step (c). By means of the present invention, it is possible using a simple device and with few steps to provide a method that easily produces anodic porous alumina such that an oxide coating film having a plurality of minute pores is formed at the surface of an aluminum substrate.
