Abstract: A multilayer electronic component includes a body including dielectric layers and internal electrodes; and an external electrode disposed on the body. The body includes a capacitance forming portion including the dielectric layers and the internal electrodes in a first direction, and a cover portion disposed on both end-surfaces of the capacitance forming portion in the first direction. One of the dielectric layers includes a first acceptor element containing Al, a second acceptor element containing at least one of Mg, Mn, or V, and Ti. The one of the dielectric layers and the cover portion include a plurality of dielectric grains, and a ratio (G1/G2) of an average size (G1) of the plurality of dielectric grains included in the one of the dielectric layers relative to an average size (G2) of the plurality of dielectric grains included in the cover portion satisfies 1.00≤G1/G2

Abstract: A multilayer electronic component includes 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 in the first direction, third and fourth surfaces in a second direction, and fifth and sixth surfaces in a third direction; side margin portions disposed on the fifth and sixth surfaces; and external electrodes disposed on the third and fourth surfaces. Side margin portions includes BaTiO3, Zn, and Zr, an amount of Zn and an amount of Zr in 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 side margin portions. The amount of Zn and the amount of Zr in the side margin portions are different from an amount of Zn and an amount of Zr in the dielectric layer.
