Abstract
A dielectric composition includes: a BaTiO-based main component and a first accessory component, wherein the first accessory component includes dysprosium (Dy) and terbium (Tb), the sum (Dy+Tb) of contents of dysprosium (Dy) and terbium (Tb) is more than 1.5 mol and 2.0 mol or less based on 100 mol of Ti of the main component, and 0.1≤Tb/Dy<0.15 in which Tb/Dy is a ratio of the content of terbium (Tb) to the content of dysprosium (Dy).
