Method of producing thermoelectric conversion element

Abstract

A method of producing a thermoelectric conversion element includes preparing a dispersion liquid by mixing slurry containing ceramic particles With salts of at least two elements that constitute a thermoelectric conversion material, and then, precipitating the at least two elements that constitute the thermoelectric conversion material on the ceramic particles in the dispersion liquid; performing washing; performing heating treatment; and performing sintering. Contact between a solution with a pH lower than 1 among solutions of the salts and the slurry containing the ceramic particles is avoided, or the solution with the pH lower than 1 contacts the slurry containing the ceramic particles for a first time when the at least two elements that constitute the thermoelectric conversion material are precipitated.
