Abstract
A sintered monolithic ceramic body or an electrical multilayer component includes cavities that are alternately open toward opposite end faces and are open to a slight portion of the lateral surfaces which are at right angles to the end faces. The cavities contain ceramic particles which act as supporting elements and are completely filled with a filler metal whose melting temperature is considerably lower than the sintering temperature of the ceramic body, the metal being capable of wetting the surfaces of the ceramic layers in the cavities in its molten state. The edges between the six outside surfaces of the component are rounded off as by abrasion so that the metal fillings extend up to contact elements which are applied after the metal is introduced.
