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.
