A thermoelectric module which has at least one thermoelectric element for converting energy between thermal energy and electrical energy. The at least one thermoelectric element has a first surface and a second surface opposite the first surface. The thermoelectric module further has a first electrode, the first electrode having at least a first region which is arranged directly on the first surface and a second electrode, the second electrode having at least a second region which is arranged directly on the second surface. At least one of the first region and the second region has a metal alloy which exhibits an Invar effect.
