    摘要: Provided are a multilayer ceramic capacitor and a manufacturing method thereof, which can stably secure capacitance and prevent cracking caused by the diffusion of an electrode material. The multilayer ceramic capacitor includes a capacitor body where an inner electrode including a first electrode material and a dielectric layer are alternately laminated, and an outer electrode disposed on an outer surface of the capacitor body and electrically connected to the inner electrode, the outer electrode including a second electrode material. A diffusion layer having a length exceeding 1 μm in which the first and second electrode materials are mixed is provided at a region where the inner electrode and the outer electrode are connected to each other.

    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.
