    • Provided is a structure with an observation port. The structure with the observation port is provided with the observation port and an internal structure. The internal structure is located to the backside of the observation port and has a third reflection preventing film. The first reflection preventing film is a film that reduces reflected light by using light interference. Each of the second and third reflection preventing films has a surface comprising a plurality of convex portions, a distance between apexes of each adjacent two of which does not exceed the visible light wavelengths. Light obtained by combining light reflected by the surface of the first reflection preventing film, light reflected by the surface of the second reflection preventing film, and light reflected by the surface of the third reflection preventing film has a flat wavelength dispersion within the visible light range.

    • A method of fabricating a motheye mold according to the present invention includes the steps of: (a) anodizing a surface of an aluminum film (10a) via an electrode (32a) that is in contact with the surface, thereby forming a porous alumina layer which has a plurality of very small recessed portions; (b) after step (a), allowing the porous alumina layer to be in contact with an etchant, thereby enlarging the very small recessed portions of the porous alumina layer; and (c) after step (b), further anodizing the surface to grow the plurality of very small recessed portions. The aluminum film is made of aluminum with a purity of 99.99 mass % or higher. The electrode includes a first electrode portion (32a1) which is made of aluminum with a purity of 99.50 mass % or lower and a second electrode portion (32a2) which is made of aluminum with a higher purity than the aluminum of the first electrode portion and which is interposed between the surface and the first electrode portion. Step (a) and step (c) are performed with the second electrode portion being in contact with the surface in an electrolytic solution. According to the present invention, a method of efficiently anodizing an aluminum film formed over a large surface substrate and an electrode structure for use in the method.
