1. A dielectric composition, comprising:
a main ingredient having a perovskite structure represented by ABO3, where A is at least one selected from the group consisting of barium, strontium, and calcium and B is at least one selected from the group consisting of titanium, zirconium, and hafnium, and a first accessory ingredient,
wherein the first accessory ingredient comprises 0.1 mole or more of a rare earth element, 0.02 mole or more of niobium, and 0.25 mole or more of magnesium, based on 100 mole of the main ingredient,
wherein a sum of contents of the rare earth element and Nb is 1.5 mole or less, based on 100 mole of the main ingredient, and
wherein the rare earth element is a rare earth element having a smaller ionic radius than that of Dy selected from the group consisting of scandium (Sc), lanthanum (La), actinium (Ac), cerium (Ce), praseodymium (Pr), neodymium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), holmium (Ho), erbium (Er), thulium (Tm), and ruthenium (Lu).
