Insulated glass unit for vehicles, and production method therefor

This insulated glass unit for vehicles is provided with: a laminated glass obtained by bonding a first glass pane and a second glass pane to each other with an interlayer therebetween; a colour-tone correction film which is provided to at least one of the surfaces of the laminated glass; a transparent conductive layer which is provided on the colour-tone correction film, and which has indium tin oxide (ITO) as a main component; and an upper layer which is provided on the transparent conductive layer, and which has a refractive index with respect to light having a wavelength of 630 nm of not more than 1.7. The colour-tone correction film is provided with at least a first layer and a second layer. The first layer is provided in a position closer to the laminated glass than the second layer. The refractive index of the first layer with respect to light having a wavelength of 630 nm is higher than that of the second layer.
