[Problem] To obtain an optical member provided with an anti-reflection film, said optical member having sufficient optical properties and being capable of being produced with high productivity. [Solution] The present invention is characterized in that: 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, is provided to a surface of a transparent substrate (10); the transparent thin-film layer (15) has, from a transparent-substrate (10) side thereof, in the given order, an alumina layer (11), a water barrier layer (12) which has a refractive index lower than that of the alumina layer (11), and which serves as a water barrier for the alumina layer (11), and a flat layer (13) which has a refractive index lower than that of the water barrier layer (12), and which has an alumina hydrate as a main component thereof; and the thickness of the water barrier layer (12) is not more than 70nm. |
