Abstract
An object of the present invention is to provide a thermoelectric conversion element which includes a p-type thermoelectric conversion layer and an n-type thermoelectric conversion layer, has excellent power generation capacity and durability, and inhibits a variation in power generation capacity between lots. The thermoelectric conversion element of the present invention is a thermoelectric conversion element having a p-type thermoelectric conversion layer and an n-type thermoelectric conversion layer electrically connected to the p-type thermoelectric conversion layer, in which the p-type thermoelectric conversion layer contains a nanocarbon material and at least one kind of component selected from the group consisting of an onium salt and an inorganic salt, the n-type thermoelectric conversion layer contains a nanocarbon material and an onium salt, and a difference between an ionization potential of the p-type thermoelectric conversion layer and an ionization potential of the n-type thermoelectric conversion layer is equal to or smaller than 0.15 eV.
