PURPOSE: To obtain a thermoelement array which can provide a high electromotive force in a small area and facilitate assembling, by arranging a plurality of layer-built thermoelements in which a pair and more of p type semiconductors and n type semiconductors, are piled up, in such a way that high-temperature ends are lined up on the same plane and mutually connected electrically.

CONSTITUTION: Nine layer-built thermoelements 1 in which size pairs of a p type semiconductors and n type semiconductors, 30mm long, 6mm wide, and 5mm thick, are formed, are used. Each thermoelement 1 generates an electromotive foce of over 1.5V by a temperature difference of 600°C. The high temperature ends of these thermoelements are fixed by alumina element to a 0.6mm thick alumina substrate 10, at an approx. 5mm pitch, in 3×3 arrangement. Respective elements are connected in series electrically by soldering lead wires. This enables a high output thermoelement array of the same dimensions to be obtained easily as compared with the conventional one.
