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.

Abstract: A multilayer electronic component includes: a body including first and second dielectric layers alternately disposed in a first direction; and external electrodes disposed on opposing end surfaces, respectively. A first internal electrode exposed to a first end surface and a first dummy pattern spaced apart from the first internal electrode and exposed to a second end surface are disposed on the first dielectric layer. A second internal electrode exposed to the second end surface and a second dummy pattern spaced apart from the second internal electrode and exposed to the first end surface are disposed on the second dielectric layer. The first and second internal electrodes include first and second main portions, respectively, and the first main portion and the second main portion are arranged in a staggered manner in a width direction.
