Transparent heat-shielding/heat-insulating member and production method thereof

Abstract

A transparent heat-shielding/heat-insulating member according to the present invention includes a transparent substrate 11 and a functional layer 19 formed on the transparent substrate 11. The functional layer 19 includes, from the transparent substrate side, an infrared reflective layer 12 and a protective layer 18 in this order. The protective layer 18 includes, from the infrared reflective layer side, a medium refractive index layer 13, a high refractive index layer 14 and a low refractive index layer 15 in this order. The infrared reflective layer 12 includes a metal oxide layer and a metal layer. The medium refractive index layer 13 has 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 layer 14 has 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 layer 15 has a light refractive index at a wavelength of 550 nm of 1.30 to 1.45 and a thickness of 70 to 150 nm.
