Abstract
Provided is a wavelength-selective absorptive material which includes, in the following order: a base material; a reflective layer; and a high refractive index layer having a refractive index n of 3.0 or more with respect to infrared light having a wavelength range of 8 μm to 13 μm, having a thickness d of 30 nm to 1,000 nm, and containing a binder and flat metal particles; and an infrared absorptive layer having a maximum absorption wavelength in a wavelength range of 8 μm to 13 μm, in which a product n×d of the refractive index n and the thickness d is more than 1,000 and less than 4,875.
