摘要： A multilayer ceramic electronic component includes external terminal electrodes that are formed by depositing metal plating films on exposed portions of internal conductors embedded in a ceramic body, depositing a copper plating films that cover the metal plating films and make contact with the ceramic body around the metal plating films, and heat-treating the ceramic body to generate a copper liquid phase, an oxygen liquid phase, and a copper solid phase between the copper plating films and the ceramic body. The mixed phase including these phases forms a region at which a copper oxide is present in a discontinuous manner inside the copper plating film at least at the interfaces between the ceramic body and the copper plating films. The copper oxide securely attaches the copper plating films to the ceramic body and enhances the bonding force of the external terminal electrodes.

摘要： When external electrodes of a multilayer ceramic capacitor are formed by performing direct plating on surfaces at which internal electrodes are exposed without forming paste electrode layers, bonding forces of plating layers are relatively weak, and in addition, when glass particles are included in the plating layers, blisters are often generated. To overcome these problems, a multilayer ceramic capacitor is formed by performing electrolytic plating using a plating bath including glass particles, electrolytic plating layers including glass particles dispersed therein are formed as the external electrodes.
