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.

Abstract: A heat insulating glass unit for vehicle includes a laminated glass in which a first glass plate and a second glass plate are bonded to each other via an intermediate film; a color tone compensation film arranged on at least one surface of the laminated glass; a transparent conductive layer mainly including an ITO arranged on the color tone compensation film; and an upper part layer arranged on the transparent conductive layer. A refraction index of the upper part layer for a light with a wavelength of 630 nm is 1.7 or less. The color tone compensation film has at least first and second layers. The first layer is arranged at a position closer to the laminated glass than the second layer. A refraction index of the first layer for a light with a wavelength of 630 nm is greater than a refraction index of the second layer.
