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.
