  • Publication number: 20160293820
    Abstract: There is provided a thermoelectric conversion element and a thermoelectric conversion module capable of ensuring a temperature difference between the front and the rear of the thermoelectric conversion element even in a high-temperature environment and presenting a high power generation performance. The thermoelectric conversion element including a sintered body constitutes a crystal grain laminated in a transverse direction in which a length in a longitudinal direction of the crystal grain is longer than a length in the transverse direction using at least some of crystal grains constituting the sintered body.
