1. A dielectric composition comprising:
a BaTiO3-base main component;
a first subcomponent including a niobium (Nb) component and a gadolinium (Gd) component;
a second subcomponent including a magnesium (Mg) component; and
a third subcomponent including a barium (Ba) component and a calcium (Ca) component,
wherein the dielectric composition comprises the first subcomponent in an amount of 4 moles or less per 100 moles of the main component,
in the first subcomponent, a molar content of Nb and a molar content of Gd satisfy 0.33≤Nb/Gd, and
in the third subcomponent, a molar content of Ba and a molar content of Ca satisfy 0.2≤Ca/(Ba+Ca).
