Abstract: A thermoelectric generator and a method for manufacturing a thermoelectric generator are described. The thermoelectric generator, having a housing in which at least one heat source tube, at least one heat sink tube, and at least one generator element are between the heat source tube and the heat sink tube. A pretension mounting device is in the housing and provides an elastic force via which the tubes are pretensioned relative to one another and which compresses the tubes and the generator element in-between. An inner side of the housing of the pretension mounting device forms a support for the pretension mounting device, which is acted upon by a counterforce to the elastic force of the pretension mounting device.
