PROBLEM TO BE SOLVED: To provide a method for manufacturing a nanostructure, by which pores having diameters on the order of nanometers (nm) and having diameter decreasing in a tapered shape can be manufactured. SOLUTION: The method includes alternately repeating cycles of an anodizing step of anodizing Al or an Al alloy 1 to form an anodic oxide film 2 having pores 3 and a pore-widening step for increasing diameter of the pore, so that the diameter of the pore is varied in the depth direction.
