Abstract: A thermoelectric generator for converting heat of a hot gas flow into electric energy can include at least one thermoelectric module with a plurality of thermoelectric elements. A gas channel on a high-temperature side of the thermoelectric module can conduct the hot gas flow in a flow direction of the gas channel. A heat sink can cool the thermoelectric module and be in contact with the thermoelectric module on a low-temperature side thereof. At least one heat conducting body can extend into the gas channel in a direction running transversely to the flow direction on the high-temperature side of the thermoelectric module and can have a free end within the gas channel. The heat conducting body can be part of the thermoelectric module or connected thereto on the high-temperature side. The thermoelectric generator can have a seal which separates an area between the heat sink and the gas channel from the gas channel and seals the area from the hot gas flow.
