Abstract
A thermoelectric element formed of a sintered body of a semiconductor comprising at least two kinds of elements selected from the group consisting of Bi, Te, Se and Sb, and having a micro-Vickers' hardness of not smaller than 0.5 GPa. The thermoelectric element has a hardness of not smaller than 0.5 GPa, and exhibits a large resistance against deformation, and is not easily broken by deformation. As a result, breakage due to deformation is prevented and a highly reliable thermoelectric element is realized even when a shape factor which is a ratio of the sectional area of the thermoelectric element to the height thereof, is increased and even when the element density is increased.
