It is to provide a substrate provided with antireflection films, which is excellent in antireflection properties to incident light at an oblique angle from the film face side, which has a high transmittance and with which the reflection color tone does not tend to be bluish. A substrate provided with antireflection films, which comprises a transparent substrate and at least two antireflection film layers deposited on one side of the transparent substrate, wherein the reflectance on the film face of light incident at an angle of incidence of 5null from the film face side is at most 6% at the entire wavelength region ranging from 400 to 480 nm.
