    Abstract: A multilayer capacitor includes: a body including dielectric layers and internal electrodes alternately disposed therein; and external electrodes disposed on the body and connected to the internal electrodes. The internal electrodes include a first internal electrode and a second internal electrode. A thickness of the second internal electrode is less than a thickness of the first internal electrode, and an area fraction of ceramics included in the first internal electrode with respect to the first internal electrode is greater than that of ceramics included in the second internal electrode with respect to the second internal electrode.

    Abstract: Disclose herein are multilayered ceramic elements having a structure in which an inner electrode layer and a dielectric layer are alternately multilayered, wherein the inner electrode layer may include inhibitors in the amount of 3 to 12 wt % with respect to a weight of metal powders, and an average particle size of the inhibitors may have a size of about 30% with respect to an average particle size of dielectric base metals. According to the exemplary embodiments of the present invention, it is possible to manufacture the elements with excellent reliability by increasing the capacity of the multilayered ceramic elements by controlling the particle size and the added quantity of the inhibitors included in the inner electrode layers that is squeezed out during firing at high temperature.
