Abstract

Provided is a visible light-transmissive and infrared-reflective substrate, including: a visible light-transmissive substrate layer disposed so as to serve as a partition between inside and outside of a room; and an infrared-reflective layer laminated on a surface on the room side of the visible light-transmissive substrate layer, wherein the visible light-transmissive substrate layer has a solar absorbance of at least 30%, the infrared-reflective layer includes a reflective layer configured to reflect infrared rays and a protective layer laminated on a surface on the room side of the reflective layer, and normal emissivity of a surface on the protective layer side of the infrared-reflective layer is not more than 0.50.
