摘要：
With conventional thermoelectric conversion materials, their thermoelectric conversion performance has been insufficient, and a problem has been to achieve stable performance in an oxidizing atmosphere and an air atmosphere. In view of this, according to the present invention, a thermoelectric material is made of a complex oxide that has vanadium oxide as its main component and is represented by the general formula AxVOx+1.5+d. Here, A is at least one selected from an alkali element, an alkaline-earth element, and a rare-earth element, x is a numerical value within the range of 0.2 to 2, and d is a non-stoichiometric ratio of oxygen and is a numerical value within the range of from −1 to 1.
