Title: Thermoelectric conversion device and manufacture method for the same

Abstract: A thermoelectric conversion device and a manufacture method thereof are provided. The manufacture method includes an electrode board stamping process, an insulating frame molding process, a punching process, an element fixing process, a bending process and an insulating frame integrating process. Band-shaped plate members which function as heat radiating fins and heat absorbing fins and are integrated with insulating frame members are respectively folded-back in such a manner that the folding-back directions of the band-shaped plate members are alternately reverse to each other in the longitudinal direction of the band-shaped plate member. The insulating frame members are joined to each other to be arranged substantially in line, to construct an insulating frame unit. Thus, the component number and the assembly labor can be reduced, while the manufacture quality and the product quality can be improved.
