Abstract
An infrared sensor includes: a base substrate; a bolometer infrared receiver; a first beam; and a second beam. Each of the first and second beams has a connection portion connected to the base substrate and/or a member on the base substrate and a separated portion away from the base substrate, and is physically joined to the infrared receiver at the separated portion. The infrared receiver is supported by the first and second beams to be away from the base substrate. The infrared receiver includes a resistance change portion including a resistance change material the electrical resistance of which changes with temperature. The resistance change portion includes an amorphous semiconductor, and the first and second beams include a crystalline semiconductor made of the same base material as the resistance change material, and is electrically connected to the resistance change portion at the separated portion.
