The invention relates to a method for producing a thermoelectric component or at least one semi-finished product of same, in which a multiplicity of thermolegs made of a thermoelectrically active material are introduced into an essentially planar substrate made of an electrically and thermally insulating substrate material such that the thermolegs extend through the substrate essentially perpendicular to the substrate plane, and in which the active material is provided in pulverulent form, is pressed to give green bodies and is then sintered within the substrate to give thermolegs. It is based on the object of refining the method of the generic type mentioned in the introduction so as to increase the freedom of choice of the thermally and electrically insulating substrate material. The object is achieved in that the pulverulent active material is pressed, in a mould arranged outside the substrate, to give green bodies, the green bodies are pushed out of the mould and into holes provided in the substrate, where they are sintered to give thermolegs.
