Abstract
A sintered monolithic ceramic body of a filler layer component has cavities which are open at end faces alternating from layer to layer and which has openings toward the lateral faces. The cavities contain ceramic particles distributed in the volume to provide support elements and the cavities are completely filled with a metal or metal alloy having a melting temperature considerably lower than the sintering temperature of the ceramic body. The metal or metal alloy exhibits the property of wetting the surfaces of the ceramic layers in the cavity in its molten condition. Contacts are applied at the end faces of the ceramic body and the openings in the lateral faces of the body are limited so that the contacts do not electrically contact the metal or metal alloy filling at the lateral faces.
