Claim 14:
15. A thermoelectric generation module comprising:
a pair of substrates;
a plurality of electrodes that are arranged on the pair of substrates;
a thermoelectric conversion element that is arranged between a pair of electrodes among the plurality of electrodes; and
a terminal that is connected to an electrode of the pair of electrodes, the terminal passing through a substrate of the pair of substrates,
wherein the substrate defines a through-hole that receives the terminal, the substrate including:
an insulator layer that is made of an electrical insulating material, the through-hole extending through the insulator layer,
an annular metal layer that is in contact with the insulator layer and arranged at a peripheral portion of the through-hole,
a first metal layer that defines a top surface of the substrate, and
a second metal layer that defines a bottom surface of the substrate,

wherein the insulator layer is disposed between the first metal layer and the second metal layer,
wherein the first metal layer and the annular metal layer are in contact with the top surface of the insulator layer, the annular metal layer being separated from the first metal layer in a radial direction,
wherein the thermoelectric generation module further comprises a solder that covers a space between the terminal and the through-hole, and
wherein the terminal comprises:
a main body having a columnar shape that extends in an axial direction, the main body passing through the through-hole and extending outside the top surface of the substrate in the axial direction, and
a head disposed at an end of the main body and disposed at the bottom surface of the substrate opposite to the top surface of the substrate in the axial direction.
