Claim 10:
11. A multilayer capacitor comprising:
a body including an active portion including a plurality of dielectric layers and a plurality of internal electrodes stacked in a first direction with respective dielectric layers among the plurality of dielectric layers interposed therebetween; and
external electrodes formed on outer surfaces of the body and connected to the internal electrodes,
wherein the body includes the active portion having the plurality of internal electrodes positioned therein to form capacitance, side margin portions including a plurality of dielectric layers and covering a first surface and a second surface of the active portion opposing each other in a second direction, and cover portions including a plurality of dielectric layers and covering the active portion in the first direction,
the dielectric layers include a barium titanate-based composition,
the dielectric layer of the active portion and the cover portion includes tin (Sn), and a content of Sn in the dielectric layer of the cover portion is different from that of Sn in the dielectric layer of the active portion,
the dielectric layer of the cover portion includes a plurality of grains having a core-shell structure, and
wherein the dielectric layer of the cover portion contains 0.1 to 10 mol of Sn based on 100 mol of barium titanate (BaTiO3).
