Abstract
A ceramic multilayer capacitor includes a number of ceramic layers on the basis of a doped BaTiO.sub.3 and a number of electrode layers of Ni. The ceramic layers and the electrode layers are alternately stacked to form a multilayer structure which is provided with electric connections at both side faces. The composition of the main component of the doped BaTiO.sub.3 corresponds to the formula (Ba.sub.1-a-b Ca.sub.a Sr.sub.b) (Ti.sub.1-c-d-e-f Zr.sub.c Al.sub.d Mn.sub.e Nb.sub.f).sub.k O.sub.3+.delta. wherein:
