Abstract: A ceramic electronic component includes a body including a dielectric layer and an internal electrode; and an external electrode disposed on the body and connected to the internal electrode. The dielectric layer includes a plurality of crystal grains and a grain boundary disposed between adjacent crystal grains. A ratio (C2/C1) of an Mg content (C2) of the grain boundary to an Mg content (C1) of at least one of the plurality of crystal grains is 3 or more.

Abstract: A multilayer electronic component includes: a body including a dielectric layer including a plurality of dielectric grains and internal electrodes alternately disposed with the dielectric layer; and an external electrode disposed on the body and connected to the internal electrodes At least one of the plurality of dielectric grains includes Ba, Ti, Sn, and a rare earth element and has a core-dual shell structure, which includes a core, a first shell disposed on at least a portion of the core, and a second shell disposed on at least a portion of the first shell. When an average molar ratio of Sn to Ti included in the first and second shells is S1 and S2, respectively, and an average molar ratio of the rare earth element to Ti included in the first and second shells is R1 and R2, respectively, S1>S2 and R2>R1 are satisfied.
