Abstract:
A multilayer ceramic capacitor includes a ceramic body including dielectric layers and first and second internal electrodes disposed to face each other with respective dielectric layers interposed therebetween; and first and second external electrodes disposed on outer surfaces of the ceramic body, wherein the dielectric layer contains zirconium (Zr), a Zr content is 2×Zr/(Ba+Ca+Ti+Zr) based on an atomic ratio, a first crystal grain is composed of a core part having a Zr content of 3.0 at % or less and a shell part having a Zr content of 4.0 to 15.0 at %, and a number fraction of the first crystal grain to all crystal grains in the dielectric layer is 4% or more.
