1. A multilayer ceramic electronic component, comprising:
a ceramic body including a dielectric layer containing strontium (Sr) and 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 the dielectric layer includes at least one first region parallel to and adjacent to the first internal electrode or the second internal electrode and having a thickness of 50 nm or less, and a second region parallel to and adjacent to the first region, and
the first region has an average content of strontium (Sr) greater than 0.1 mol % and less than 9.3 mol % with respect to a total content of compounds included in the first region, and the second region has a lower average content of strontium (Sr) than the average content of the strontium of the first region.
