Abstract

A thermoelectric conversion element includes: a thermoelectric conversion material portion composed of a material having a band gap; a first electrode disposed in contact with the thermoelectric conversion material portion; a second electrode disposed in contact with the thermoelectric conversion material portion and disposed to be separated from the first electrode; and a sealing portion that seals the thermoelectric conversion material portion. A partial pressure of oxygen in a region surrounding the thermoelectric conversion material portion is maintained by the sealing portion so as to be lower than a partial pressure of oxygen in an external air.
