摘要： A dielectric ceramic composition and a multilayer ceramic capacitor comprising the same are provided. The dielectric ceramic composition includes a BaTiO3-based base material main ingredient and an accessory ingredient, where the accessory ingredient includes dysprosium (Dy) and cerium (Ce) as first accessory ingredients. A total content of Dy and Ce is greater than 0.25 mol % and equal to or less than 1.0 mol % based on 100 mol % of the base material main ingredient.
