Abstract
Provided is a multilayer ceramic capacitor having dielectric layers and internal electrode layers laminated alternately on one another. Each internal electrode layer comprises a common ceramic material containing 3 to 25% by weight of rare earth elements, and through the rare earth elements, high dielectric layers are formed on the interfaces between the dielectric layers and the internal electrode layers.
