Abstract
A transparent heat-shielding/heat-insulating member includes a transparent substrateand, from the transparent substrate side, an infrared reflective layerand a protective layerin this order. The protective layerincludes, from the infrared reflective layer side, a medium refractive index layer, a high refractive index layerand a low refractive index layerin this order. The medium refractive index layerhas a light refractive index at a wavelength of 550 nm of 1.45 to 1.55 and a thickness of 80 to 200 nm. The high refractive index layerhas a light refractive index at a wavelength of 550 nm of 1.65 to 1.95 and a thickness of 100 to 350 nm. The low refractive index layerhas a light refractive index at a wavelength of 550 nm of 1.30 to 1.45 and a thickness of 70 to 150 nm.
