Method of manufacturing thermoelectric conversion element and thermoelectric conversion element

A method of manufacturing a thermoelectric conversion element, comprising:

• preparing a plurality of p-type semiconductor sheets each containing a powder of p-type semiconductor material, and a plurality of n-type semiconductor sheets each containing a powder of n-type semiconductor material;
• preparing a plurality of separator sheets each including through holes provided at a predetermined pitch, the though holes being filled with a conductive material;
• stacking the p-type semiconductor sheets and the n-type semiconductor sheets alternately with the separator sheets each interposed in between to form a laminated body;
• obtaining a laminated body unit by cutting the laminated body at positions of the through holes of the separator sheets;
• baking the laminated body unit to obtain a semiconductor block aggregate of a structure in which p-type semiconductor blocks and n-type semiconductor blocks are alternately connected with electrodes;
• and
• attaching a pair of heat transfer plates to the semiconductor block aggregate.
