MULTILAYER CERAMIC CAPACITOR AND METHOD FOR PRODUCING MULTILAYER CERAMIC CAPACITOR

WIPO Patent Application WO/2024/018720

A1

The present invention provides: a multilayer ceramic capacitor which has a high dielectric constant and a high capacity, while suppressing a decrease in reliability due to oxygen vacancy; and a method for producing a multilayer ceramic capacitor.　A multilayer ceramic capacitor 10 according to the present invention is provided with: a multilayer body 12 which comprises internal electrode layers 16 that each comprise a plurality of first internal electrode layers 16a and a plurality of second internal electrode layers 16b, which face each other and are arranged so as to be separated from each other, and a dielectric layer 14 that is arranged between the internal electrode layers 16 and contains a ceramic material; and an external electrode 30 which is selectively connected to a plurality of internal electrode layers 16. Each electrode layer of the plurality of internal electrode layers 16 contains a rare earth oxide; and the rare earth oxide in each one of the plurality of internal electrode layers 16 is distributed along at least one of a pair of interfaces Iu and Il with the dielectric layer 14.
