Method for production of a thermoelectric component or at least a semifinished version thereof, characterized by the following steps: a) providing a substantially planar substrate made of an electrically and thermally insulating substrate material, through which through-holes extend oriented substantially perpendicularly to the substrate plane; b) providing pulverulent thermoelectrically active active material; c) pressing the active material to form green bodies, wherein the pressing proceeds in a mould different from the substrate; d) inserting the green bodies into the through-holes of the substrate in such a manner that, within each through-hole, along the axis thereof, one green body extends through the substrate; e) arranging the substrate with the green bodies inserted therein between two substantially planar electrodes (12a, 12b), in such a manner that both electrodes and the substrate are substantially orientated parallel to one another; f) contacting face ends of the green bodies with the electrodes in such a manner that a connection is provided between the two electrodes via the green bodies, which connection transmits not only an electrical current but also a mechanical pressing force; g) exposing the green bodies to an electric current flowing between the electrodes in such a manner that heat is evoked within the thermoelectric active material; h) exposing the green bodies to a pressure force acting between the electrodes in such a manner that the thermoelectric active material comes under pressure; i) sintering the green bodies to form thermolegs, with the action of pressure and heat; k) levelling the substrate and the thermolegs accommodated therein by bringing them closer to the electrodes while maintaining the parallelity thereof, in such a manner that thermolegs finish flush with the substrate, wherein any axial offset of the green bodies in the substrate and also any sinter shrinkage are compensated for. a) providing a substantially planar substrate made of an electrically and thermally insulating substrate material, through which through-holes extend oriented substantially perpendicularly to the substrate plane; b) providing pulverulent thermoelectrically active active material; c) pressing the active material to form green bodies, wherein the pressing proceeds in a mould different from the substrate; d) inserting the green bodies into the through-holes of the substrate in such a manner that, within each through-hole, along the axis thereof, one green body extends through the substrate; e) arranging the substrate with the green bodies inserted therein between two substantially planar electrodes (12a, 12b), in such a manner that both electrodes and the substrate are substantially orientated parallel to one another; f) contacting face ends of the green bodies with the electrodes in such a manner that a connection is provided between the two electrodes via the green bodies, which connection transmits not only an electrical current but also a mechanical pressing force; g) exposing the green bodies to an electric current flowing between the electrodes in such a manner that heat is evoked within the thermoelectric active material; h) exposing the green bodies to a pressure force acting between the electrodes in such a manner that the thermoelectric active material comes under pressure; i) sintering the green bodies to form thermolegs, with the action of pressure and heat; k) levelling the substrate and the thermolegs accommodated therein by bringing them closer to the electrodes while maintaining the parallelity thereof, in such a manner that thermolegs finish flush with the substrate, wherein any axial offset of the green bodies in the substrate and also any sinter shrinkage are compensated for.
