Zusammenfassung:An object of the present invention is to provide an infrared sensor capable of efficient light-to-heat conversion by thickening the light-absorbing layer, and a method for manufacturing the same. An infrared sensor comprising: an infrared reflecting mirror; a first light-absorbing layer formed on the infrared reflecting mirror and being a polymer resin layer in which light-absorbing nanoparticles are dispersed; two electrodes formed on the first light-absorbing layer; a light-detecting part that at least partially overlaps and electrically contacts with the two electrodes; a second light-absorbing layer formed on the light-detecting part and being a polymer resin layer in which light-absorbing nanoparticles are dispersed; and a metal thin film formed on the second light-absorbing layer.
