Multilayer electronic component

A multilayer electronic component comprising:

• a body including a dielectric layer and first and second internal electrodes alternately disposed in a first direction with the dielectric layer interposed therebetween, and having first and second surfaces opposing each other in the first direction, third and fourth surfaces opposing each other in a second direction and connected to the first and second surfaces, and fifth and sixth surfaces opposing each other in a third direction and connected to the first to fourth surfaces;
• side margin portions disposed on the fifth and sixth surfaces;
• and
• external electrodes disposed on the third and fourth surfaces,
• wherein at least one of the side margin portions includes BaTiO3, Zn, and Zr,
• an amount of Zn and an amount of Zr in the at least one of the side margin portions are 0.5 mol or more and 1.0 mol or less, relative to 100 mol of Ti included in the at least one of the side margin portions, respectively, and
• the amount of Zn in the at least one of the side margin portions is different from an amount of Zn in the dielectric layer, and the amount of Zr in the at least one of the side margin portions is different from an amount of Zr in the dielectric layer, and
• wherein the at least one of the side margin portions comprises a plurality of dielectric grains and grain boundaries, and an amount of Zn and an amount of Zr at the grain boundaries are higher than in the dielectric grains.
