Abstract

A method of producing a thermoelectric conversion device, provided with: a step of disposing electrodes (4) respectively to opposing surfaces of a pair of current-pressure applying members (2) which face each other; a step of interposing a plurality of members of thermoelectric conversion material (3) between the electrodes (4); and a step of bonding the electrodes (4) to the thermoelectric conversion material (3) by applying pressure to the electrodes (4) and thermoelectric conversion material (3) with the current-pressure applying member (2) while applying current to the electrodes (4) and the thermoelectric conversion material (3). The method of producing a thermoelectric conversion device is further provided with a step of forming intermediate layers (5), which include conductive metal powder and have plasticity, between the electrodes (4) and the thermoelectric conversion material (3).

Description

technical field [0001] The present invention relates to a method for manufacturing a thermoelectric conversion element, and more particularly to a method for manufacturing a thermoelectric conversion element in which a thermoelectric conversion element is installed between electrodes and the electrode and the thermoelectric conversion element are joined by energizing the electrode and the thermoelectric conversion element. Background technique [0002] A thermoelectric conversion element utilizing the Seebeck effect has a characteristic of converting thermal energy into electrical energy. Utilizing this characteristic, it is possible to convert thermal energy discharged from industrial and domestic processes and moving objects into effective electric power, and thus thermoelectric conversion elements are attracting attention as an energy-saving technology that takes environmental issues into consideration. [0003] Such a thermoelectric conversion element is generally consti...
