- anodized porous alumina having a desired taper-shaped hole is realized by combining anodization and a pore diameter expansion process by etching. After anodizing for a predetermined time to form pores with the desired depth (Fig. 1 (c)), the pores are enlarged by immersion in an appropriate alumina solution (Fig. L ( d)). After this, anodization is performed again to form a hole with a smaller diameter than that in Fig. 1 (c) (Fig. L (e)).
