Abstract: A multilayer ceramic electronic component includes: a ceramic body including a dielectric layer having a main component represented by (Ba1-xCax)(Ti1-y (Zr, Hf)y)O3 (where, 0≤x≤1, 0≤y≤0.5), and including first and second internal electrodes alternately stacked with the dielectric layer interposed therebetween; a first external electrode connected to the first internal electrode; and a second external electrode connected to the second internal electrode, wherein at least one of the dielectric layer and the internal electrode includes Sn or Dy. If Sn, an average content of Sn at an interface between the dielectric layer and the internal electrode is within a range of 5 at % or more and 20 at % or less. If Dy, an average content of Dy at an interface between the dielectric layer and the internal electrode is within a range of 1 at % or more and 5 at % 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 nickel (Ni) powder including a coating layer having a surface including copper (Cu) on the ceramic green sheet, forming a ceramic multilayer structure by stacking the ceramic green sheet with the internal electrode pattern formed thereon, and forming a body including a dielectric layer and an internal electrode by sintering the ceramic multilayer structure. The content of Cu is equal to or greater than 0.2 wt %, based on a total weight of the Ni powder.
