MOLDING DIE FOR MANUFACTURING NANOSTRUCTURE FORMATION, AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a molding die for manufacturing nanostructure formation having scratch resistance and durability and the like by adjusting the thickness of an anodic oxide film thereof, and to provide a method for manufacturing the same.

SOLUTION: The molding die is used for manufacturing the nanostructure formation using a nanostructure, and has the anodic oxide film formed on a surface of an aluminum material. The anodic oxide film has pores at an average period of ≥50 nm and ≤400 nm at least in one direction. Each pore is formed of a taper-shaped part and a fine pore shaped part therebelow. The taper shaped part has a taper shape which is widely open on the surface of the anodic oxide film, and gradually narrowed toward a deeper part. The fine pore shaped part has the fine pore shape of substantially equal diameter. The anodic oxide film also has a fine pore shaped layer which is continuous to the lower side of the taper shape layer having the taper shape part and includes the fine pore shaped part.
