Abstract
A process for producing a structure having a porous layer is provided. The process forms the porous layer with high thickness-controllability. The process comprises steps of preparing a layered product having, on a substrate, a first nonporous layer and a second nonporous layer different in constituting material composition from the first layer; anodizing the layered product to form pores in the first nonporous layer and the second nonporous layer; and removing the second nonporous layer having pores formed therein from the layered product.
