Abstract
A thermoelectric conversion element includes a first electrode, a thermoelectric conversion material portion configured to convert heat into electricity, an intermediate layer arranged on the thermoelectric conversion material portion, a conductive bonding material arranged in between the intermediate layer and the first electrode to bond the first electrode to the intermediate layer, and a second electrode connected to the thermoelectric conversion material portion. The intermediate layer includes a first layer arranged on the thermoelectric conversion material portion and containing a dopant, and a second layer arranged on the first layer and configured to suppress diffusion of elements. The intermediate layer has an interface resistivity of not less than 0.0001 mΩcmand not more than 0.5 mΩcm.
