Abstract:
A multilayer ceramic capacitor includes a body having a dielectric layer and internal electrodes disposed to be alternately exposed to the third and fourth surfaces with the dielectric layer interposed therebetween. External electrodes include connection parts respectively formed on opposing surfaces of the body, band parts formed to extend from the connection parts to portions of side surfaces of the body, and corner parts in which the connection parts and the band parts are contiguous. A thickness of each of the external electrodes may be 50 nm to 2 μm. The external electrodes may be formed using a barrel-type sputtering method. A ratio t2/t1 may satisfy 0.7 to 1.2, where t1 is a thickness of each connection part and t2 is a thickness of each band part. A ratio t3/t1 may satisfy 0.7 to 1.0, where t3 is a thickness of each corner part.
