Claim 9:
10. 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,
wherein the rare earth element comprises lanthanum (La), and further comprises at least one of yttrium (Y), actinium (Ac), cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), or lutetium (Lu), and
a content ratio (La/DT) of the lanthanum (La) to a sum (DT) of the contents of the rare earth element satisfies 0.1 or more and less than 1.0.
