1. A multilayer electronic component comprising:
a body including a dielectric layer and an internal electrode; and
an external electrode disposed on the body and connected to the internal electrode,
wherein the dielectric layer includes a dielectric composition,
wherein the dielectric composition includes:
one of BaTiO3, (Ba,Ca)(Ti,Ca)O3, (Ba,Ca)(Ti,Zr)O3, Ba(Ti,Zr)O3 or (Ba,Ca)(Ti,Sn)O3, as a main component;
a first subcomponent comprising a rare earth element; and
a second subcomponent comprising at least one of a variable valence acceptor element or a fixed valence acceptor element,
wherein the dielectric layer comprises a plurality of crystal grains,
wherein one or more of the plurality of crystal grains have a core-shell structure, and
when a sum of contents of the rare earth element is defined as DT, and a sum of contents of the variable valence acceptor element and the fixed valence acceptor element is defined as AT, (DT/AT)/(Ba+Ca) satisfies more than 0.5 and less than 6.0.
