Thermoelectric converter manufacturing method, manufacturing method of electronic device provided with thermoelectric converter, and thermoelectric converter

Used as a first conductive paste (41) is a product obtained by making into a paste the result of adding an organic solvent to a powder of an alloy in which multiple metal atoms maintain a prescribed crystal structure, and used as a second conductive paste (51) is a product obtained by making into a paste the result of adding an organic solvent to a powder of metals dissimilar to the alloy. Further, this method involves a step for configuring a laminate body (80) in which cavities (13-17) are formed inside of the laminate body (80), and an integration step, in which the pressure for integration is increased by absorbing pressure in directions other than the pressurizing direction for integrating the laminate body (80) which acts on the first conductive paste (41) by acting such that the cavities promote flow of a thermoplastic resin, and the first conductive paste (41) is solid-phase sintered, configuring a first interlayer connection member (40).
