Claim 17:
18. 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
wherein the body includes the active portion having the plurality of internal electrodes positioned therein to form capacitance, a side margin portion including a plurality of dielectric layers and covering at least one of a first surface and a second surface of the active portion opposing each other in a second direction, and a cover portion including a plurality of dielectric layers and covering the active portion in the first direction,
the dielectric layers of the active portion, the side margin portion, and the cover portion include a barium titanate-based composition,
the dielectric layer of the active portion, the cover portion and the side margin portion include tin (Sn), and a content of Sn in the dielectric layer of the cover portion is different from a content of Sn in the dielectric layer of the side margin portion with respect to 100 mol % of the barium titanate-based composition, and
wherein the dielectric layer of the cover portion includes at least some grains having a core-shell structure.
