摘要： A multilayer ceramic capacitor is provided. In the multilayer ceramic capacitor, a plurality of first and second inner electrodes are formed inside a ceramic sintered body. Ends of the first and second inner electrodes are alternately exposed to both ends of the ceramic sintered body. First and second outer electrodes are formed on both ends of the ceramic sintered body and connected to the first and second inner electrodes. The first and second outer electrodes include a first region having a porosity in the range of 1% to 10%, and a second region having a porosity less than that of the first region.
