According to one embodiment, a thermoelectric device is provided with thermoelectric elements and formed of a material capable of exhibiting the thermoelectric effect and a first electrode located at end portions of the thermoelectric elements. The first electrode includes an electrode member, a soaking member having electrical conductivity, located between the electrode member and the thermoelectric elements, and including facing portions facing the thermoelectric elements and folded portions folded back at peripheral edges of the facing portions so as to lie on the opposite side to the thermoelectric elements, and an elastic member located on the opposite side of the facing portions to the thermoelectric elements, at least a part of the peripheral edge of the elastic member being held between the folded portions and the facing portions of the soaking member.

Thermoelectric device and thermoelectric module

According to one embodiment, a thermoelectric module includes a housing and a power generation member. The housing has a first temperature layer and a second temperature layer, the first temperature layer and the second temperature layer being stacked, the housing further having a cylindrical through-hole provided so as to penetrate the first temperature layer and the second temperature layer. The power generation member has thermoelectric materials stacked such that current flows in one direction in the power generation member, the power generation member being provided in the through-hole so that opposite ends of each of the thermoelectric materials are positioned at the first temperature layer and the second temperature layer, respectively.
