Abstract: An optical member includes a transparent substrate containing at least one substance selected from glass, a glass ceramic, silicon, and sapphire, and having an infrared high-transmittance region in which an optical transmittance is 78% or more in a wavelength band of 700 nm to 1800 nm; and an optical interference film disposed on a main surface of the transparent substrate corresponding to the infrared high-transmittance region, wherein a transmittance of light, of the optical member, of at least one wavelength λ3 in the wavelength band of 700 nm to 1800 nm in a region of the optical member corresponding to the infrared high-transmittance region of the transparent substrate has a minimum value of 86.5% or more and has a difference between the minimum value and a maximum value of 9% or less in a range where an incidence angle is from 0 degrees to 60 degrees.

Abstract: To appropriately suppress reflection of far-infrared rays, and appropriately form an antireflection film. A far-infrared ray transmission member (20) includes a base material (30) that transmits far-infrared rays, and a functional film (32) that is formed on the base material (30) and includes a low refractive index layer (34) containing oxide as a principal component and having a refractive index equal to or smaller than 1.5 with respect to light at a wavelength of 10 μm. The low refractive index layer (34) contains MgO as a principal component, and a content of MgO is equal to or larger than 50 mass % and equal to or smaller than 100 mass % with respect to the entire low refractive index layer (34).

Abstract: An electrochromic element which suppresses ripples in a color-reduction state and with which good visible light transmittance can be obtained is provided. An electrochromic element 100 includes: a transparent electrolyte layer 110; a pair of solid electrochromic layers which sandwiches the transparent electrolyte layer and is constituted by a pair of a reduction coloring-type solid electrochromic layer 120 and an oxidation coloring-type solid electrochromic layer 130 opposing each other, and a pair of transparent conductive films 140, where in the thickness and refractive indexe with respect to light at a wavelength of 550 nm about the transparent electrolyte layer 140, the reduction coloring-type solid electrochromic layer 120 and the oxidation coloring-type solid electrochromic layer 130, those values are provided so as to satisfy predetermined relations to suppress the ripples.
