Abstract: A multilayer capacitor includes a body including a stack structure of a plurality of dielectric layers, and a plurality of internal electrodes stacked with the dielectric layers interposed therebetween. A stress alleviation portion is disposed on at least one surface among surfaces of the body, and an external electrode is disposed on an external portion of the body and connected to the internal electrodes. The stress alleviation portion includes a first resin layer adjacent to the body, and a second resin layer covering the first resin layer and including a filler dispersed in a resin of the second resin layer.

Abstract: A multilayer ceramic electronic component includes a ceramic body including dielectric layers and a plurality of internal electrodes disposed to face each other with each of the dielectric layers interposed therebetween, and external electrodes disposed on external surfaces of the ceramic body and electrically connected to the internal electrodes, respectively. The external electrodes include electrode layers electrically connected to the internal electrodes and conductive resin layers disposed on the electrode layers, and the conductive layers are disposed to extend first and second surfaces of the ceramic body. When a distance from an outer edge of one of the first or second external electrodes disposed on a first or second surface to an inner edge thereof is defined as BW and surface roughness of the ceramic body is defined as Ra, a ratio of 100 times the surface roughness Ra to the distance BW (Ra*100/BW) satisfies (Ra*100/BW)?1.0.
