<p>A glass substrate with antireflection film is provided, which has sufficient antireflection performance for obliquely incident light, high visible light transmittance, sufficient abrasion resistance and good transmittance for electromagnetic waves, which is sufficiently durable against heat treatment in the production process, to which treatment after film-forming is applicable, and which has smaller number of films and thus is producible at low cost. A glass sheet with antireflection film, comprising a glass sheet and an antireflection film composed of at least two layers and provided on a surface of the glass sheet, wherein the antireflection film comprises a film (a) made of a high refractive index material having a refractive index of from 1.8 to 2.6 and an extinction coefficient of from 0.01 to 0.65 in a wavelength region of from 380 to 780 nm, and a film (b) made of a low refractive index material having a refractive index of at most 1.56 in a wavelength region of from 380 to 780 nm, and wherein the film (b) is positioned at an outermost surface of the antireflection film and the antireflection film has a sheet resistance of at least 1 k©/–¡.</p> |
