Abstract
There is provided a multilayer ceramic capacitor. The multilayer ceramic capacitor includes inner electrodes and dielectric layers stacked alternately with each other. When a continuity level of each of the inner electrodes is defined as B/A where A denotes a total length of the inner electrode and B denotes a length of the inner electrode excluding pores of the inner electrode, and a section of the inner electrode, having a predetermined length from each end of the inner electrode, is defined as an outer section, a section of the inner electrode excluding the outer section is defined as an inner section, and a section of the dielectric layers from each end of the inner electrode to a corresponding surface of the multilayer ceramic capacitor is defined as an edge section, a length of the outer section is 0.1 to 0.3 times that of the edge section, and the outer section of the inner electrode has a lower continuity level than that of the inner section of the inner electrode.
