Abstract: A multilayer capacitor includes a body including a plurality of dielectric layers and a plurality of internal electrodes laminated in a first direction, and external electrodes. 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 1.49<A1/A2<2.50 where A1 is an average grain size of the dielectric layer in a central region of the active portion, and A2 is an average grain size of the dielectric layer in an active-cover boundary portion, adjacent to the cover portion, of the active portion.

Abstract: A dielectric composition includes: a BaTiO3-based main component and a first accessory component, wherein the first accessory component includes dysprosium (Dy) and terbium (Tb), the sum (Dy+Tb) of contents of dysprosium (Dy) and terbium (Tb) is more than 1.5 mol and 2.0 mol or less based on 100 mol of Ti of the main component, and 0.1?Tb/Dy<0.15 in which Tb/Dy is a ratio of the content of terbium (Tb) to the content of dysprosium (Dy).
