Abstract
A thermoelectric power module capable of withstanding a long time use in a high temperature environment where a temperature (Th) of a higher temperature portion exceeds 250° C. The thermoelectric power module includes: a thermoelectric power element; a first diffusion prevention layer consisting of molybdenum (Mo) and disposed on a surface of the thermoelectric power element; a second diffusion prevention layer consisting of an intermetallic compound of nickel-tin (Ni—Sn) and disposed on a surface of the first diffusion prevention layer opposite to the thermoelectric power element side; an electrode; a third diffusion prevention layer consisting of an intermetallic compound of nickel-tin (Ni—Sn) and disposed on a surface of the electrode; a solder layer containing lead (Pb) at not less than 85% and configured to join the second diffusion prevention layer and the third diffusion prevention layer to each other.
