Abstract
Provided are an electrode material for thermoelectric conversion modules capable of preventing cracking and peeling of electrodes that may occur at the bonding parts of a thermoelectric element and an electrode under high-temperature conditions to thereby maintain a low resistance at the bonding parts, and a thermoelectric conversion module using the material. The electrode material for thermoelectric conversion modules includes a first substrate and a second substrate facing each other, a thermoelectric element formed between the first substrate and the second substrate, and an electrode formed on at least one substrate of the first substrate and the second substrate, wherein the substrate is a plastic film, the thermoelectric element contains a bismuth-tellurium-based thermoelectric semiconductor material, a telluride-based thermoelectric semiconductor material, an antimony-tellurium-based thermoelectric semiconductor material, or a bismuth-selenide-based thermoelectric semiconductor material, the electrode that is in contact with the thermoelectric element is formed of a metal material, and the metal material is gold, nickel, aluminum, rhodium, platinum, chromium, palladium, sta…
