PROBLEM TO BE SOLVED: To provide a thermoelectric conversion device and a manufacturing method thereof, wherein working is easily and surely carried out, quality problems are surely solved, and high efficiency, low cost, and high density can be achieved. SOLUTION: In the thermoelectric conversion device 11, a plurality of n-type thermoelectric semiconductor elements 1-1 are divided between them, and a plurality of p-type thermoelectric semiconductor elements 2-2 are divided between them. Grooves 47, 50 having a width equal to this division width are formed in a lower base 44 at those division positions. A block 34 of respective thermoelectric element materials 1B, 2B is fabricated by dividing beforehand a joined block formed of respective relatively thick (thickness T) thermoelectric element materials 1A, 2A. The block 34, in the state it is supported by the base 44, is cut and divided together with the lower electrode material layer 42 and a part of the base 44 to have a predetermined width. Thus, respective thermoelectric elements 1, 2 having aimed width (t) can easily and efficiently be formed. COPYRIGHT: (C)2004,JPO
