Abstract
The invention relates to a ceramic multilayer capacitor having a number of ceramic layers on the basis of a doped (Ba,Ca)[Ti,Zr]O.sub.3 as well as a number of electrode layers of Ni, the ceramic layers and the electrode layers being alternately stacked to form a multilayer structure which is provided with electric connections at two side faces, said electric connections being connected to a number of the electrode layers. The invention is characterized in that the composition of the main component of the doped (Ba,Ca)[Ti,Zr]O.sub.3 corresponds to the formula
