An anodized coating suitable for formation of highly regulated pores is provided. A method for production of a structure having pores characterized by including the steps of: forming starting points at predetermined intervals in an aluminum alloy formed on a substrate, and forming pores by anodization with the starting points as origins. In another embodiment, first and second aluminum alloy layers are anodized to form pores penetrating into the layers, wherein a diameter of a pore in the first alloy is different from a diameter of a pore in the second alloy. In an additional embodiment, a substrate is anodized to form pores, wherein the substrate contains an additive which changes the diameter within each pore, the amount of the additive continuously changing along the direction perpendicular to the substrate.
