Multilayer ceramic capacitors

Abstract

The multilayer ceramic capacitor 1 of the present invention comprises: a blank 10 including a plurality of dielectric ceramic layers 20 and a plurality of internal electrode layers 30 stacked along the stacking direction T, and external electrodes 11 and 12 disposed on the surface of the blank 10 and electrically connected to the internal electrode layers 30. The internal electrode layers 30 comprise nickel (Ni) and a first rare earth element. The first rare earth element comprises at least one rare earth element (Re) selected from the group consisting of lanthanum (La), cerium (Ce), cerium (Pr), neodymium (Nd), samarium (Sm), europium (Eu), thorium (Gd), tbium (Tb), dysprosium (Dy), yttrium (Y), holmium (Ho), erbium (Er), thionium (Tm), ytterbium (Yb), and ruthenium (Lu). Within a range of 10 nm from the interface between the internal electrode layer 30 and the dielectric ceramic layer 20 toward the internal electrode layer 30, the elemental ratio of Re to Ni and the sum of Re satisfies 0.001≤Re / (Ni+Re)≤0.060.
