Abstract
A heat insulating glass unit for vehicle includes a glass plate; a color tone compensation film arranged on at least one surface of the glass plate; a transparent conductive layer arranged on the color tone compensation film, and mainly including an indium tin oxide (ITO); and an upper part layer arranged on the transparent conductive layer, a refraction index for a light with a wavelength of 630 nm being 1.7 or less. The color tone compensation film has at least a first layer and a second layer. The first layer is arranged at a position closer to the glass plate 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 for a light with a wavelength of 630 nm.
