Abstract:
A multilayer ceramic capacitor includes a ceramic body including a dielectric layer and first and second internal electrodes disposed to oppose each other with the dielectric layer interposed therebetween, and first and second external electrodes disposed outside of the ceramic body and connected to the first and second internal electrodes, respectively. The ceramic body includes an active portion including of the first and second internal electrodes disposed to oppose each other with the dielectric layer interposed therebetween to form capacitance, and a cover portion disposed in upper and lower portions of the active portion. The cover portion has a larger number of pores than the dielectric layer of the active portion, and the cover portion includes a ceramic-polymer composite filled with a polymer in the pores of the cover portion.
