Zusammenfassung: | The present invention relates to a thermoelectric element including a metal medium layer. More specifically, the thermoelectric element includes: an element arrangement board made by placing electrodes on an upper side of a substrate; and a plurality of thermoelectric legs bonded to an upper part of the element arrangement board. The thermoelectric element also includes a metal medium layer and a bonding material layer placed between the element arrangement board and the thermoelectric legs. Moreover, the present invention relates to a method for bonding a thermoelectric element including a metal medium layer, wherein the method includes the following steps of: preparatorily heating the element arrangement board made by placing the electrodes on the upper side of the substrate; stacking the metal medium layer and the bonding material layer in an upper part of the electrodes; and locating the thermoelectric legs to be matched with an upper part of the stacked bonding material layer, and then, pressing the thermoelectric legs to bond the thermoelectric legs. Therefore, the present invention is capable of improving mechanical material properties such as tensile strength, yield strength, toughness and the like.
