Abstract
Provided is a dielectric composition containing: a main component expressed by {BaSr}TaO; and a first subcomponent, m satisfying a relationship of 1.95≤m≤2.40. The first subcomponent includes silicon and manganese. When the amount of the main component contained in the dielectric composition is set to 100 parts by mole, the amount of silicon contained in the dielectric composition is 5.0 to 20.0 parts by mole in terms of SiO, and the amount of manganese contained in the dielectric composition is 1.0 to 4.5 parts by mole in terms of MnO.
