A monolithic ceramic capacitor, comprising a ceramic body, a plurality of internal electrodes of lead or lead alloy which are formed in said ceramic body in such a manner that adjacent two internal electrodes interpose a ceramic layer of the ceramic body, and a pair of external electrodes which are formed on both opposite end planes of the ceramic body and are connected to alternate internal electrodes, respectively, being characterized in that said external electrode comprises a first layer and a second layer which do not react with the internal electrode, that the first porous layer is connected to alternate internal electrodes, and that the second layer is formed on the first layer so as to cover the first layer and is made of silver, copper or nickel or its alloy. A manufacturing method of a monolithic ceramic capacitor, comprising the steps of: (1) making a sintered ceramic body in which a plurality of voids are formed, said voids each being opened to either one end plane of the ceramic body, (2) applying a first porous layer on each of opposite end planes of said ceramic body, (3) dipping said ceramic body into molten lead or lead alloy, (4) introducing molten lead or lead alloy through said first layers into each of said voids to form internal electrodes therein, and (5) applying a second layer on each first layer so as to cover it. |
