摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for manufacturing anodized porous alumina capable of reliably preparing an anodized porous alumina in which micro pores are arrayed in a high regularity, and to provide the anodized porous alumina manufactured by the method for manufacturing anodized porous alumina.;SOLUTION: When anodizing an aluminum material 11, an electrolyzing liquid is brought into contact with an anodization part of the aluminum material, at the same time, liquid other than the electrolyzing liquid is brought into contact with a part different from the anodization part of the aluminum material as a heating medium 12, and a temperature of the aluminum material is controlled to a prescribed temperature independent of a temperature of the electrolyzing liquid. Since the temperature of the electrolyzing liquid and the temperature of the aluminum material can be controlled independent of each other, the removal of heat generation of the aluminum material accompanied by an anodizing reaction and the quickening of the anodization reaction by heating of the aluminum material are permitted. Particularly, the formation of micropores arrayed with a high regularity and the stable anodization at a high voltage are permitted.;COPYRIGHT: (C)2011,JPO&INPIT
