Multilayer ceramic capacitor and manufacturing method thereof

A manufacturing method of a multilayer ceramic capacitor, the manufacturing method comprising:

• preparing a dielectric slurry by mixing a barium titanate-based primary component powder and secondary component powder comprising a samarium (Sm)-containing compound and a second secondary component containing compound;
• manufacturing a dielectric green sheet by using the dielectric slurry, and forming a conductive paste layer on a surface of the dielectric green sheet;
• manufacturing a dielectric green sheet laminate by stacking the dielectric green sheet on which the conductive paste layer is formed;
• manufacturing a capacitor body comprising a dielectric layer and an internal electrode layer by firing the dielectric green sheet laminate;
• and
• forming an external electrode on a first surface of the capacitor body,
• wherein the second secondary component containing compound comprises a lanthanum (La)-containing compound, a cerium (Ce)-containing compound, a praseodymium (Pr)-containing compound, a neodymium (Nd)-containing compound, a promethium (Pm)-containing compound, a europium (Eu)-containing compound, a gadolinium (Gd)-containing compound, a terbium (Tb)-containing compound, a dysprosium (Dy)-containing compound, a holmium (Ho)-containing compound, an erbium (Er)-containing compound, a thulium (Tm)-containing compound, a ytterbium (Yb)-containing compound, a lutetium (Lu)-containing compound, or a combination thereof, and
• wherein the second secondary component containing compound is comprised in an amount ranging from 1.2 parts by mole to 2.0 parts by mole based on 100 parts by mole of the barium titanate-based primary component powder.
