Abstract:
This transparent heat-shielding/heat-insulating member having a transparent screen function includes an infrared reflection layer and an optical adjustment protection layer in this order from a transparent substrate side, and includes a light diffusion layer on the reverse side of the transparent substrate to the surface thereof on which the infrared reflection layer is formed or between the transparent substrate and the infrared reflection layer. The optical adjustment protection layer includes at least a high refractive index layer and a low refractive index layer in this order from the infrared reflection layer side, and the transparent heat-shielding/heat-insulating member has a visible light reflectance of 12% to 30% inclusive, a haze value of 5% to 35% inclusive, a shielding factor of 0.69 or less, and a normal emittance of 0.22 or less.
