Abstract: The present invention provides a tubular thermoelectric generation device, comprising: a plurality of plate-like p-type thermoelectric members each having an external periphery, a through hole, and an internal periphery formed around the through hole; a plurality of plate-like n-type thermoelectric members each having an external periphery, a through hole, and an internal periphery formed around the through hole; a plurality of external electrodes; and a plurality of internal electrodes. Each of the plurality of the external electrodes comprises an internal flange expanded in a direction from the external periphery of the p-type thermoelectric member toward the internal periphery of the p-type thermoelectric member. Each of the plurality of the internal electrodes comprises an external flange expanded in a direction from the internal periphery of the p-type thermoelectric member toward the external periphery of the p-type thermoelectric member.

Abstract: The present invention provides a thermoelectric conversion material represented by the following chemical formula Mg3+mAaBbD2-eEe. The element A represents at least one selected from the group consisting of Ca, Sr, Ba and Yb. The element B represents at least one selected from the group consisting of Mn and Zn. The value of m is not less than −0.39 and not more than 0.42. The value of a is not less than 0 and not more than 0.12. The value of b is not less than 0 and not more than 0.48. The element D represents at least one selected from the group consisting of Sb and Bi. The element E represents at least one selected from the group consisting of Se and Te. The value of e is not less than 0.001 and not more than 0.06. The thermoelectric conversion material has a La2O3 crystalline structure. The thermoelectric conversion material is of n-type. The present invention provides a novel thermoelectric conversion material.
