<p>[Problem] To obtain an optical member provided with an anti-reflection film, said optical member being capable of being produced with ease and without using many different kinds of materials. [Solution] The present invention has, provided to a surface of a transparent substrate (10) therein, an anti-reflection film (19) provided with a transparent thin-film layer (15), and a transparent fine uneven layer (18) having an alumina hydrate as a main component thereof, in that order. The transparent thin-film layer (15) has a refractive index between that of the transparent substrate (10) and that of the fine uneven layer (18). Furthermore, the transparent thin-film layer (15) includes at least a nitride layer or an oxynitride layer.</p> |
