Abstract

A multilayer electronic component (100), comprising: a body (110) including a dielectric layer (111) and internal electrodes (121, 122); and external electrodes (131, 132) disposed on an outer surface of the body (110), wherein the dielectric layer (111) includes a plurality of dielectric grains (10, 20, 30), wherein at least one of the plurality of dielectric grains (10, 20, 30) has a core-double shell structure including a core (11, 21) a first shell (12) surrounding at least a portion of the core, and a second shell (13) surrounding at least a portion of the first shell (12), wherein the first and second shells (12, 13) include rare earth elements, and an average atomic percentage of the rare earth elements in the first shell (12) is higher than an average atomic percentage of the rare earth elements in the second shell (13), and wherein the average atomic percentage of the rare earth elements in the first shell (12) is 4.0 at% or more and 6.0 at% or less. Further, the average atomic percentage of the rare earth elements in the second shell (13) is 2.0 at% or more and less than 4.0 at%.
