    摘要： A multilayer capacitor includes a body, a plurality of internal electrodes, and external electrodes. The corners of the cover portions of the body include curved surfaces, a length of each of internal electrodes disposed in the cover portions among the plurality of internal electrodes is smaller than a length of an internal electrode disposed in a central portion, and when a distance from a surface of the body to a closest internal electrode among the plurality of internal electrodes is defined as a margin, a portion of the margin region, located directly above or below the internal electrodes disposed in the cover portions in the stacking direction, includes at least two layers including different densities of dielectric layers.

    摘要： A multilayer capacitor includes a body, a plurality of internal electrodes and external electrodes disposed on external surfaces of the body and electrically connected to the internal electrodes, wherein in the body, corners of cover portions include curved surfaces, and 10 μm≤R≤T/4 in which R is a radius of curvature of the curved surface corners and T is a thickness of the body, and when a distance from a surface of the body to an internal electrode closest to the surface of the body among the plurality of internal electrodes is a margin, a margin (δ) of each of the corners formed as the curved surfaces in the cover portions is greater than or equal to a margin (Wg) of the body in a width direction.
