Method of producing shaped product for thermoelectric conversion element and method of producing thermoelectric conversion element

A method of producing a thermoelectric conversion element having a thermoelectric conversion material layer including a shaped product for a thermoelectric conversion element, comprising:

• mixing a coarse mixture that contains metal nanoparticle-supporting carbon nanotubes, a resin component, and a solvent by dispersion treatment that brings about a cavitation effect or a crushing effect, to obtain a composition for a thermoelectric conversion element;
• and
• removing the solvent from the composition for a thermoelectric conversion element to obtain the shaped product for a thermoelectric conversion element.
