A ceramic electronic component includes a body including a dielectric layer and an internal electrode, and an external electrode disposed on the body and connected to the internal electrode. The dielectric layer includes a plurality of dielectric grains, and at least one of the plurality of dielectric grains has a core-dual shell structure having a core and a dual shell. The dual shell includes a first shell surrounding at least a portion of the core, and a second shell surrounding at least a portion of the first shell, and a concentration of a rare earth element included in the second shell is more than 1.3 times to less than 3.8 times a concentration of a rare earth element included in the first shell.

Ceramic electronic component and method of manufacturing the same

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.

Multilayer capacitor

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)&#x2264;1.0.
