Multilayer ceramic capacitor and method of manufacturing the same

A method of manufacturing a multilayer ceramic capacitor, comprising:

• preparing a dielectric slurry by mixing a barium titanate-based primary component powder and a secondary component powder including a tin (Sn)-containing compound;
• manufacturing a dielectric green sheet from the dielectric slurry and forming a conductive paste layer on a surface of the dielectric green sheet;
• manufacturing a dielectric green sheet laminate by laminating a plurality of the dielectric green sheets on which the conductive paste layer is formed;
• manufacturing a capacitor body including a dielectric layer and an internal electrode layer by firing the dielectric green sheet laminate;
• and
• forming an external electrode on one surface of the capacitor body,
• wherein the dielectric layer includes a plurality of dielectric grains, and at least one of the dielectric grains includes a core portion and a shell portion surrounding at least a portion of the core portion,
• wherein the shell portion includes a barium titanate-based primary component including barium (Ba) and titanium (Ti) and a secondary component including tin (Sn),
• wherein the shell portion comprises a Sn concentrated region including tin (Sn) and a Sn non-concentrated region including tin (Sn) at an atom % less than an atom % of tin (Sn) in the Sn concentrated region, and
• wherein an atomic ratio of tin (Sn) included in the Sn concentrated region to tin (Sn) included in the Sn non-concentrated region is 2.0 to 6.0.
