Abstract
There is provided a transparent laminate which comprises a transparent substrate, and four to five units each of a high refractive index transparent film and a silver type transparent electrical conductor film. The units are laminated successively on a surface of the transparent substrate, and one high refractive index transparent film is further disposed as an outermost layer. The high refractive index transparent film is an optically transparent film having a refractive index of from 1.5 to 2.7. The silver type transparent electrical conductor film has a thickness in a range of from 5 to 20 nm. A thickness of the silver type transparent electrical conductor film disposed in a first layer with reference to the transparent substrate is substantially equal to a thickness of the silver type transparent electrical conductor film in an outermost layer with reference to the transparent substrate. A thickness of the silver type transparent electrical conductor film in each of other layers is 3/2(1±0.2) times as large as the thickness of the silver type transparent electrical conductor film in the first layer. A thickness of the high refractive index transparent film in a first layer with reference to the transparent substrate is substantially equal to a thickness of the high refractive index transparent film in an outermost layer with reference to the transparent substrate and is 7/2(1±0.2) times as large as the thickness of the silver type transparent electrical conductor film in the first layer. The thickness of the high refractive index transparent film in each of other layers is 7 (1±0.2) times as large as the thickness of the silver type transparent electrical conductor film in the first layer.
