Dielectric ceramic composition and multilayer ceramic capacitor comprising same

A multilayer ceramic capacitor, comprising:

• a ceramic body including a dielectric layer, and a first internal electrode and a second internal electrode disposed to oppose each other with the dielectric layer interposed therebetween;
• and
• a first external electrode and a second external electrode disposed on an exterior of the ceramic body, wherein the first external electrode is electrically connected to the first internal electrode, and the second external electrode is electrically connected to the second internal electrode, wherein the dielectric layer includes a dielectric grain including a dielectric ceramic composition,
• the dielectric ceramic composition includes a barium titanate (BaTiO3)-based base material main component and a subcomponent, the subcomponent including an oxide which includes zinc as a first subcomponent, and
• a content of the oxide which includes zinc in the dielectric ceramic composition is 0.1 mol % or more and less than 0.4 mol % with respect to 100 mol % of the barium titanate-based base material main component, and a thickness of the dielectric layer is 0.4 μm or less.
