Multilayer ceramic capacitor with dielectric layers including dielectric grains having a core-shell structure

A multilayer ceramic capacitor comprising:

• a ceramic body including dielectric layers and first and second internal electrodes disposed to face each other with each of the dielectric layers interposed therebetween;
• and
• first and second external electrodes disposed on external surfaces of the ceramic body and electrically connected to the first and second internal electrode, respectively,
• wherein the dielectric layer includes:
• dielectric grains having a core-shell structure including a core and a shell;
• and dielectric grains having a shell structure including only a shell,
• at least one domain wall is disposed in the core and the shell of the core-shell structure and the shell structure including only a shell,
• the dielectric grains having a core-shell structure and the dielectric grains having a shell structure including only the shell are intermixed throughout the entire thickness of the dielectric layer, and
• a direction in which the domain wall in the core extends is substantially parallel to that of the domain wall in the shell in the core-shell structure.
