Abstract: The invention relates to a composite body comprising a support plate having recesses, the support plate having an upper main surface and a lower main surface and an electrically conductive paper structure adjoining the upper main surface of the support plate, wherein the electrically conductive paper structure has at least one conductor track facing the upper main surface of the support plate, wherein conductor elements are introduced into the recesses of the support plate in such a way that the conductor elements are flush with the upper main surface of the support plate, wherein the conductor elements are in electrical contact with the at least one conductor track of the electrically conductive paper structure and wherein the conductor elements are contactable with a current source from the lower main surface of the support plate.

Abstract: A composite body including a substrate with a front side, a rear side and an outer edge, and an electrically conductive paper layer, wherein the electrically conductive paper layer is at least partially arranged on the front side of the substrate and at least partially encompasses at least two conductive tracks. The at least two conductive tracks are at least partially arranged on the rear side and/or the outer edge of the substrate. Further described is a use of the composite body and a method for producing a composite body. Further described is a contacting device for electrically contacting an electrically conductive paper layer of a composite body.
