Abstract
According to one embodiment, a thermoelectric material are provided. The thermoelectric material includes a sintered body formed of p-type and n-type thermoelectric materials for the thermoelectric conversion element. The thermoelectric materials have a MgAgAs type crystal structure as a main phase. An area ratio of internal defects of the thermoelectric materials for one thermoelectric conversion element is 10% or less in terms of a total area ratio of defective portions in a scanning surface according to ultrasonic flaw detection in a thickness direction of the thermoelectric material. No defect having a length of 800 μm or more is present at any vertex of chips of the thermoelectric materials.
