Abstract:
Provided is a glass sheet with an antireflection film: containing a glass sheet, a first transparent high refractive index layer located on the glass sheet, a first transparent low refractive index layer located on the first transparent high refractive index layer, a second transparent high refractive index layer located on the first transparent low refractive index layer, and a second transparent low refractive index layer located on the second transparent high refractive index layer; having a haze after heating at 600° C. to 700° C. for 15 minutes being 0.4% or less; and having a visible light reflectance measured from the side of the second transparent low refractive index layer based on JIS R 3106 being 1.0% or less.
