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.
