Abstract: An optical sensor includes a support layer, a thermoelectric-conversion material section disposed on the support layer and including strip-shaped p-type material layers configured to convert thermal energy into electric energy and strip-shaped n-type material lavers configured to convert thermal energy into electric energy, a heat sink, a light absorbing film, and an insulating film disposed between the thermoelectric-conversion material section and the light absorbing film. Each of the p-type material layers includes a first region overlapping the heat sink and a second region overlapping the light absorbing film. Each of the n-type material layers includes a third region overlapping the heat sink and a fourth region overlapping the light absorbing film. The p-type material layers and the n-type material layers are alternately disposed in series. The light absorbing film includes 60 mass % to 95 mass % of carbon and 5 mass % to 40 mass % of a resin.
