Abstract

A method for manufacturing a thermoelectric conversion element and the thermoelectric conversion element, comprising: a holding step of exposing at least one end portion of at least one thermoelectric conversion component (2, 3) and holding the thermoelectric conversion component; a covering step of passing metal powder (13 ) covering the exposed end of the thermoelectric conversion member; and an electrode forming step of sintering the metal powder to form an electrode (4a) at the end of the thermoelectric conversion member.

Description

technical field [0001] The present invention relates to a method for manufacturing a thermoelectric conversion element and a thermoelectric conversion element manufactured by the manufacturing method, and particularly relates to a thermoelectric conversion element with stable thermoelectric characteristics and a method for manufacturing the same. Background technique [0002] The thermoelectric conversion module converts thermal energy into electrical energy through the Seebeck effect. By utilizing such energy conversion properties, it is possible to convert waste heat discharged from industries, domestic processes, and mobile bodies into effective electric power. Therefore, this thermoelectric conversion element has attracted attention as an energy-saving technology that takes environmental issues into consideration. [0003] Such a thermoelectric conversion element is generally constituted by joining a plurality of thermoelectric conversion elements (p-type semiconductor a...
