PROBLEM TO BE SOLVED: To provide a thermoelectric conversion element that is in a configuration where the thermoelectric conversion efficiency of an Si-group material that is an inexpensive and light thermoelectric conversion material has been improved extremely and at the same time uses and Si group that is in a configuration for facilitating manufacturing, and its manufacturing method. SOLUTION: When the thermoelectric conversion element is subjected to compression molding in p/n/p/n/p/ configuration for integration sintering by alternately arranging n-type and p-type material power and including an insulation material such as Si-system and ceramic power outside the scheduled part of pn junction, integration can be facilitated extremely, and at the same time loss due to electrode junction can be reduced to almost zero. At the same time, joining is made to a pn junction that is located at high-temperature and low- temperature sides for forming an element via a hetero metal when a temperature gradient is given to the thermoelectric conversion element, thus improving electromotive force and the amount of electricity.
