A transparent heat-insulating and heat-insulating member comprising a transparent substrate, an infrared reflecting layer, a protective layer, and a light diffusion layer, the transparent heat-insulating and insulating member from the transparent substrate side from the infrared reflecting layer and the protective layer In this order, the light diffusion layer is formed on the opposite side of the surface of the transparent substrate on which the infrared reflection layer is formed or between the transparent substrate and the infrared reflection layer, and the infrared reflection layer Includes at least a metal layer and a metal suboxide layer in which the metal is partially oxidized, and the protective layer has a total thickness of 200 nm to 980 nm, and has at least a high refractive index layer and a low refractive index layer from the infrared reflective layer side. A refractive index layer is included in this order, and the light diffusion layer includes light diffusing particles and a transparent resin that holds the light diffusing particles. The transparent thermal insulation member has a visible light reflectance of 12% to 30%, a haze value of 5% to 35%, a shielding coefficient of 0.69 or less, and a vertical emissivity. Is 0.22 or less. |
