Abstract of the Disclosure A monolithic, multilayer, ceramic capacitor is formed by introducing molten metal into a matrix having thin electrode regions between dielectric strata through holes, each, of which extends through a face of said matrix and provides communication between the outside of said matrix and at least one of said regions, around wires or rods inserted in said holes, thereby providing external leads for said capacitor. A similar process is used to provide internal and external connectors for multilayer ceramic, circuit, boards.
