Abstract
A method of manufacturing a nonostructure, which enables cylindrical pores arrayed according to any periodic pattern to be easily made on a substrate over a large area at a low cost in a short period of time. The method of manufacturing a structure having such pores includes the steps of preparing a substrate having recesses in its surface, providing a film on the surface of the substrate and anodizing the film.
