Abstract
Disclosed are a multilayer ceramic capacitor and a method of manufacturing the same. The multilayer ceramic capacitor includes a ceramic body having a plurality of dielectric layers stacked on top of each other, at least one internal electrode formed on a corresponding one of the plurality of dielectric layers and having uneven portions formed at an edge thereof, the internal electrode having a connectivity of between 0.7 and 0.9, which is defined by an equation below, and an external electrode formed on an outer surface of the ceramic body and connected with the internal electrode,Z=X−Y/X (Equation)where X denotes a length of a cross-section of the internal electrode in one direction, Y denotes a total length of gaps formed by holes in the cross-section, and Z denotes the connectivity of the internal electrode. The multilayer ceramic capacitor achieves a low crack generation rate and a high level of reliability.
