Thermoelectric conversion module

This thermoelectric conversion module (1) comprises: a lower substrate (10) and an upper substrate (20) that are a pair of support substrates arranged facing each other; a plurality of thermoelectric conversion elements (30) arranged between the lower substrate (10) and the upper substrate (20); a temperature detection element (40) arranged on one support substrate of the lower substrate (10) and the upper substrate (20); and a sealing member (50) positioned between the peripheral edge part of the lower edge substrate (10) and the upper substrate (20), and formed to surround the plurality of thermoelectric conversion elements (30) in top view. In top view, the temperature detection element (40) is positioned between the plurality of thermoelectric conversion elements (30) and the edge of one support substrate, and the sealing member (50) covers the temperature detection element (40), and contacts at least one of the plurality of thermoelectric conversion elements (30).
