Claim 0:
1. 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, a side margin portion 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 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 and the side margin portion includes tin (Sn), and a content of Sn in the dielectric layer of the side margin portion is different from that of Sn in the dielectric layer of the active portion with respect to 100 mol % of the barium titanate-based composition,
the dielectric layer of the side margin portion includes a plurality of grains having a core-shell structure, and
wherein a shell portion of the core-shell structure includes a barium titanate-based composition in which Ti is substituted with Sn.
