Abstract
An optical sensor includes a support film having a first main surface and a second main surface located opposite to the first main surface in a thickness direction; a thermoelectric-conversion material section disposed on the first main surface and including a plurality of strip-shaped first material layers formed of SiGe having p-type conductivity and configured to convert thermal energy into electric energy, and a plurality of strip-shaped second material layers formed of SiGe having n-type conductivity and configured to convert thermal energy into electric energy; a heat sink disposed on the second main surface; and a light absorbing film disposed so as to form a temperature difference in each of the first material layers in longitudinal directions and each of the second material layers in longitudinal directions and configured to convert received light into thermal energy.
