Abstract
An object is to provide a method for manufacturing a wavelength selective heat radiation material in which a surface roughness of an upper portion of a cavity wall defining each microcavity is suppressed or in which microcavities each having an aspect ratio larger than 3.0 are formed. For the wavelength selective heat radiation material, a base material having a mask having predetermined openings tightly adhered to a surface thereof, or a base material in which depressions are previously formed on one surface thereof by pressing a die having projections arrayed so as to correspond to positions of microcavities thereagainst, is subjected to anisotropic etching, thereby providing a wavelength selective heat radiation material in which the surface roughness of the upper portion of the cavity wall defining each of the microcavities is suppressed or a wavelength selective heat radiation material having microcavities whose each aspect ratio is larger than 3.0.
