  • Patent number: 8575469
    Abstract: A compact, high-performance thermoelectric conversion module includes a laminate having a plurality of insulating layers, p-type thermoelectric semiconductors and n-type thermoelectric semiconductors formed by a technique for manufacturing a multilayer circuit board, particularly a technique for forming a via-conductor. Pairs of the p-type thermoelectric semiconductors and the n-type thermoelectric semiconductors are electrically connected to each other in series through p-n connection conductors to define thermoelectric conversion element pairs. The thermoelectric conversion element pairs are connected in series through, for example, series wiring conductors. The thermoelectric semiconductors each have a plurality of portions in which the peak temperatures of thermoelectric figures of merit are different from each other. These portions are distributed in the stacking direction of the laminate.
