Zusammenfassung:To appropriately transmit far-infrared rays while ensuring design. A far-infrared ray transmission member (20) includes a base material (30) configured to transmit far-infrared rays, and a functional film (31) formed on the base material (30). Dispersion of reflectances with respect to pieces of light at a wavelength of 360 nm to 830 nm in increments of 1 nm is equal to or smaller than 30, a reflectance with respect to visible light defined by JIS R3106 is equal to or lower than 25%, and an average transmittance with respect to light at a wavelength of 8 um to 12 um is equal to or higher than 50%.
