ABSTRACT:
The invention aims to provide a multilayer ceramic capacitor with high dielectric constant, a high capacitance, and an excellent reliability by eliminating oxygen vacancy in dielectric layers and suppressing oxidation of Ni inner electrodes. The multilayer ceramic capacitor comprises a multilayered dielectric body composed by alternately piling up dielectric layers containing mainly barium titanate and inner electrode layers containing mainly Ni and a first hetero-phase containing Mg—Si—O as constituent elements exists in the capacitor.
