Disclosed is a thermoelectric generation module which can withstand prolonged use in high-temperature environments such as those where the temperature (Th) of the high temperature section exceeds 250?. The disclosed thermoelectric generation module includes: a thermoelectric generation element (20); first diffusion barrier layers (71) which are disposed on the surface of the thermoelectric generation element (20) and which comprise molybdenum (Mo); second diffusion barrier layers (73) which are disposed on the surface on the opposite side of the first diffusion barrier layers (71) to the thermoelectric generation element (20) and which comprise a nickel-tin (Ni-Sn) intermetallic compound; electrodes (40); third diffusion barrier layers (42) which are disposed on the surface of the electrodes (40) and which comprise a nickel-tin (Ni-Sn) intermetallic compound, and solder layers (80) which connect the second diffusion barrier layers (73) and the third diffusion barrier layers (42) and which contain at least 85% lead (Pb).
