ABSTRACT:
In a multilayer capacitor, which is made of alternate layers of a dielectric oxidic ceramic material and an electrode material, and which is provided with metallic end contacts which electrically conductively contact a prescribed part of the layers of electrode material via an intermediate layer of a conductive metal oxide, the metallic end contacts containing silver, the diffusion of silver from the end contacts to the layers of electrode material is suppressed effectively in that the electrode material consists of palladium with 1 to 10% by weight of lead. On account of this, the end contacts can be readily manufactured from a paste, and delamination, cracking and the formation of cavities in the vicinity of the end contacts are suppressed.
