Abstract: A thermoelectric conversion element includes a p-type thermoelectric converter, an n-type thermoelectric converter, a first electrode, a second electrode, and a third electrode. One end of the p-type converter is electrically connected to one end of the n-type converter. The other end of the p-type converter is electrically connected to the second electrode, and the other end of the n-type converter is electrically connected to the third electrode. The p-type converter includes a first phononic crystal layer having a first phononic crystal structure including regularly arranged first through holes. The n-type converter includes a second phononic crystal layer having a second phononic crystal structure including regularly arranged second through holes. The through direction of the first through holes is a direction extending between the ends of the p-type converter. The through direction of the second through holes is a direction extending between the ends of the n-type converter.

Abstract: An infrared sensor is formed in such a manner that an infrared receiver and a base substrate are spaced with a beam made of a thin-film phononic crystal in which through holes are arranged periodically. The beam made of a phononic crystal is formed in such a manner that a period P of through holes increases at arbitrary intervals in a direction from the infrared receiver toward the base substrate.
