Abstract:
PROBLEM TO BE SOLVED: To provide a conductive paste composition for internal electrodes and a multilayer ceramic capacitor including the same.SOLUTION: A conductive paste composition for internal electrodes includes: 100 moles of a metal powder; 0.5 to 4.0 moles of a ceramic powder; and 0.03 to 0.1 moles of a silica (SiOpowder. A conductive paste composition for internal electrodes can raise the sintering shrinkage temperature of the internal electrodes and improve the connectivity of the internal electrodes, and can improve the degree of densification of the dielectric layer, thereby improving withstand voltage characteristics, reliability, and dielectric characteristics.
Abstract:
PROBLEM TO BE SOLVED: To enable formation of a continuous plating film at least as a portion of an external electrode to connect between exposed terminals of a plurality of internal electrodes, even when each gap between adjacent exposed terminals of the internal electrodes is wide.SOLUTION: A component body 2 having a plurality of ceramic layers 95 and the plurality of internal electrodes 91-93, in which each portion of the plurality of internal electrodes is exposed, is formed to have conductive regions 96-98 with diffused formation of conductive components included in the internal electrodes, on the end face of the ceramic layer 95 located between the neighboring exposed terminals of the plurality of internal electrodes. The ceramic layer is preferably composed of a glass ceramic including a glass component of 10 wt.% or more. To form external electrodes 3-6, the plating film is directly formed on the component body 2 by plating-growing the exposed terminals of the internal electrodes and the conductive regions as a core of plating deposition.
