A thermoelectric conversion module is formed by arranging, on one surface, a plurality of thermoelectric conversion element pairs in which an n-type thermoelectric conversion element and a p-type thermoelectric conversion element are connected by interposing an electrode plate, and connecting the plurality of the thermoelectric conversion element pairs in series; and the thermoelectric conversion module has a first output terminal provided on one thermoelectric conversion element pair arranged at one end side of the plurality of the thermoelectric conversion element pairs connected in series, a second output terminal provided on the other thermoelectric conversion element pair arranged at the other end side of the plurality of the thermoelectric conversion element pairs connected in series, and an intermediate output terminal provided at any position between the thermoelectric conversion element pair arranged at the one end side and the thermoelectric conversion element pair arranged at the other end side.
