Abstract: A multilayer capacitor includes a body and external electrodes on external surfaces of the body. The body includes a plurality of internal electrodes alternately laminated with dielectric layers. The external electrodes are electrically connected to the internal electrodes. Edges of cover portions of the body are rounded. The rounded edges have a radius of curvature R and the body has a thickness T, such that R and T satisfy 10 μm≤R≤T/4. Among the plurality of internal electrodes, an internal electrode in each of the cover portions has a width less than that of an internal electrode of the central portion.
