Abstract

The invention relates to a filled layer component made out of monolithic ceramic, in particular a capacitor, having a ceramic layer structure of dense and porous layers which is impregnated with a metallic material and is provided with contacts on the outer faces. According to the invention, the contacts have at least on their surfaces enrichments with constituents which form with the material of the contacts one or more intermetallic compounds which are largely insoluble in the impregnating material. These enrichments can be applied in a first manufacturing method before the impregnation process, or in another manufacturing method during the impregnation process.
