Title: Thermoelectric element and method for manufacturing the same

Abstract: A plurality of n-type bar-shaped devices (51) consisting of an n-type thermoelectric semiconductor and a plurality of p-type bar-shaped devices (52) consisting of a p-type thermoelectric semiconductor are regularly disposed or fixed through an insulating layer (50) to form a thermoelectric device block (53). End portions of the n-type bar shaped device (51) and the p-type bar-shaped device (52) are connected with an interconnection conductor (58a) on an upper surface (53a) and a lower surface (53b), which will be interconnecting end faces of the thermoelectric device block (53), to form a plurality of thermocouples connected in series. In addition, a pair of terminal conductors (58b, 58b) which is electrically connected with bar-shaped devices (51a, 52a) at least on one end portion and the other end portion of the n-type and p-type bar-shaped devices (51, 52) connected in series is formed on end face (53c) excluding the upper surface (53a) and the lower surface (53b) which will be an interconnecting end face of the thermoelectric device block (53), and a lead wire is connected to the terminal conductors (58b, 58b).
