The low-reflection coating of the present invention is adapted to be provided on at least one principal surface of a substrate. The low-reflection coating is a porous film having a thickness of 80 to 800 nm, the porous film including: fine silica particles being solid and spherical and having an average particle diameter of 80 to 600 nm; and a binder containing silica as a main component and containing a hydrophobic group, the fine silica particles being bound by the binder. The low-reflection coating contains 35 to 70 mass% of the fine silica particles, 25 to 64 mass% of the silica of the binder, and 0.2 to 10 mass% of the hydrophobic group of the binder. The low-reflection coating produces a transmittance gain of 1.5% or more when provided on the substrate.
