Multilayer capacitor

A multilayer capacitor comprising:

• a body including a plurality of dielectric layers and a plurality of internal electrodes laminated in a first direction with respective dielectric layers interposed therebetween;
• and
• external electrodes formed on external surfaces of the body and connected to the internal electrodes,
• wherein the body includes an active portion, in which the plurality of internal electrodes are disposed to form capacitance, corresponding to a region between internal electrodes disposed on an outermost side in the first direction, among the plurality of internal electrodes, a cover portion covering the active portion in the first direction, and a side margin portion covering the active portion in a second direction, perpendicular to the first direction, and
• wherein 1.49<A1/A2<2.50,
• where A1 is an average grain size in a dielectric layer in the central region of the active portion, and A2 is an average grain size in a dielectric layer in an active-cover boundary portion, adjacent to the cover portion, of the active portion, wherein the plurality of dielectric layers includes a barium titanate component, and
• a dielectric composition of the central region of the active portion is different from that of the central region of the cover portion, and
• wherein a molar ratio of Ba to Ti in a central region of the cover portion is different from the molar ratio of Ba to Ti in the central region of the active portion.
