[Problem] To provide an anti-reflection film that suppresses light scattering, exhibits sufficient anti-reflection properties, and is highly durable, and to provide an optical member. [Solution] An anti-reflection film (3) configured from: a relief structure layer (10) that has a hydrate of alumina as a main constituent and has a relief structure in which the distance between protrusions is shorter than the wavelength of the light for which reflection is to be suppressed; and an intermediate layer (5) that is disposed between the relief structure layer (10) and a substrate (2). The relief structure layer (10) is configured so that the relief structure has a spatial frequency peak value of 6.5 μm-1 or higher and a film thickness of 250 nm or greater. The intermediate layer (5) is configured from a plurality of layers including, in order from the relief structure layer (10)-side to the substrate (2)-side, at least a first layer (51), a second layer (52), a third layer (53), a fourth layer (54), a fifth layer (55), a sixth layer (56), a seventh layer (57), and an eighth layer (58). |
