Patent ID: 7820905

Claim:
A manufacture method of a thermoelectric conversion device, comprising: an electrode board constructing process for constructing an electrode board, where a plurality of band-shaped plate members extending in a longitudinal direction thereof are arrayed in rows with respect to a lateral direction thereof in such a manner that the band-shaped plate members are spaced from each other at a predetermined distance in the lateral direction and a plurality of bridge portions are arrayed in rows with respect to the longitudinal direction of the band-shaped plate member in such a manner that the bridge portions are spaced from each other at a predetermined distance in the longitudinal direction of the band-shaped plate member, each of the bridge portions connecting the band-shaped plate members with each other in the lateral direction of the band-shaped plate member; an insulating frame molding process for molding a plurality of insulating frame members integrally with the electrode board in such a manner that the insulating frame members are spaced from each other at a predetermined distance in the longitudinal direction of the band-shaped plate member, the insulating frame member being arranged at two sides of the bridge portion and spaced from the bridge portion at a predetermined distance, the two sides being defined with respect to the longitudinal direction of the band-shaped plate member, the insulating frame member having a pair of first frame portions which connect the plurality of band-shaped plate members in the lateral direction of the band-shaped plate member, and a pair of second frame portions which connect the pair of first frame portions; a cutting process for cutting the bridge portion in such a manner that the band-shaped plate member has a remainder remained in the insulating frame member; an element fixing process for electrically joining P-type thermoelectric elements and N-type thermoelectric elements in the insulating frame member to the remainders; a bending process for respectively folding-back the band-shaped plate members positioned between the adjacent insulating frame members in such a manner that folding-back directions of the band-shaped plate members are alternately reverse to each other in the longitudinal direction thereof; and an insulating frame integrating process for joining the plurality of insulating frame members to each other to construct an insulating member unit in such a manner that the plurality of insulating frame members are arranged substantially in line.
