    Abstract: A multilayer electronic component includes a body including dielectric layers and internal electrodes alternately disposed in a first direction, and external electrodes disposed on the body to be connected to the internal electrodes. At least one internal electrode of the internal electrodes includes a plurality of disconnected portions penetrating through a respective internal electrode. A disconnected portion of the plurality of disconnected portions includes at least one of a pore or a dielectric substance disposed to connect adjacent dielectric layers to each other. A dielectric filling ratio, defined as a ratio of an overall length of the dielectric substance to an overall length of the disconnected portion on a cross section in the third and first directions, is more than 20% to 80% or less.

    Abstract: A method of manufacturing a multilayer ceramic electronic component includes preparing a ceramic green sheet, forming an internal electrode pattern by coating a paste for an internal electrode including a conductive powder including one or more of tungsten (W), molybdenum (Mo), chromium (Cr), and cobalt (Co), the sum of which is 1 to 20 wt o, and including tin (Sn), on the ceramic green sheet, forming a ceramic multilayer structure by stacking ceramic green sheets on which the internal electrode pattern is formed, and forming a body including a dielectric layer and an internal electrode by sintering the ceramic multilayer structure.

    Abstract: A capacitor component includes a body including dielectric layers and first and second internal electrodes disposed to face each other while having the dielectric layer interposed therebetween; and first and second external electrodes disposed on an external surface of the body and electrically connected to the first and second internal electrodes, respectively. The body includes a capacitance forming portion including the first and second internal electrodes disposed to face each other while having the dielectric layer interposed therebetween and in which capacitance is formed, and cover portions formed on upper and lower surfaces of the capacitance forming portion, and hardness of the cover portions is 9.5 GPa or more and 14 GPa or less.

    Abstract: A capacitor component includes a body including a dielectric layer and first and second internal electrodes, alternately disposed in a first direction, and first and second external electrodes, respectively disposed on opposite end surfaces of the body in a second direction, perpendicular to the first direction in the body. An amorphous second phase is disposed at an interface between the first and second internal electrodes and the dielectric layer, and s/e is between 0.02 and 0.07, where s is a total length of the amorphous second phase disposed in a boundary line between the first or second internal electrode and the dielectric layer in the second direction and e is a length of the first or second internal electrode in the second direction.
