THERMOELECTRIC MATERIAL AND METHOD FOR PRODUCING SAME

Conventional thermoelectric materials have not achieved sufficient thermoelectric conversion performance and have not realized stable performance in oxidizing atmospheres and in the air. To solve such problems, a thermoelectric material is disclosed which is composed of a composite oxide which mainly contains a vanadium oxide and is represented by the general formula : AxVOx+1.5+d. In the formula, A represents at least one element selected from alkali elements, alkaline earth elements and rare earth elements; x is a value not less than 0.2 but not more than 2; and d represents a variable ratio of oxygen within the range from -1 to 1.
