Abstract: PURPOSE: To provide a thermoelectric element performance evaluation method and a device, wherein a one-dimensional heat flow condition can be realized so as to accurately evaluate the performance of a thermoelectric element of gradient structure under a condition of large temperature difference. CONSTITUTION: A thermoelectric element arranged between a primary heat source 2 and a cooling source to measure a thermoelectromotive force or the like is surrounded with a heat shield 7, and an auxiliary heat source 3 is provided to heat the outside of the heat shield 7 from across so as to make the temperature distribution of the heat shield 7 nearly equal to a temperature distribution induced in the thermoelectric element due to a temperature difference between the primary heat source 2 and the cooling source. A temperature distribution around the thermoelectric element is set nearly equal to that of the element, whereby the thermoelectric element is kept under a condition of one-dimensional heat flow.
