Abstract:
An optical member includes a substrate and an antireflection film on the substrate. The antireflection film includes a porous layer at the surface thereof. The porous layer contains silicon oxide particles and a binder. The porous layer is provided with a fluororesin on at least part of the surface of the porous layer. The contact angle of n-hexadecane on the surface of the antireflection film is in the range of 50° to 80°.
