PROBLEM TO BE SOLVED: To provide a thermoelectric generator in which a contact surface between a heat recovering member and a heat receiver of a thermoelectric generating module is finished as a surface with high flatness, and heat can be extremely efficiently transmitted to the heat receiver of the thermoelectric generating module from the heat receiver for a long time without pressurizing the contact surface. SOLUTION: When a fin member 2 is heated to a high temperature during using the thermoelectric generator, a low melting point metallic body 5 filled in the recess 2C of the fin member 2 is melted, and a high melting point metallic film 4 covering the surface of the rising part 5A of the low melting point metallic body 5 is closely stuck to the heat receiving surface 1A1 of the thermoelectric generating module 1 by the flexibility of the melted low melting point metallic body 5. In this case, protection films 7A and 7B covering entirely the low melting point metallic body 5 prevents metallic components of the high melting point metallic film 4 or the fin member 2 from being melted into the melted low melting point metallic body 5 in advance. Thus, the change in physical property or the like of the low melting point metallic body 5 and damage of the high melting point metallic film 4 can be prevented for a long time.
