Abstract: A dielectric composition contains major components that are an A-group containing major components that are at least two selected from the group consisting of Ba, Ca, and Sr and a B-group which contains a major component that is selected from Zr and Ti and which contains at least Zr. The dielectric composition contains an amorphous substance containing the A-group and the B-group and a crystalline substance containing the A-group and the B-group. In the dielectric composition, the inequality 0.5≦α≦1.5 holds, where α is the molar ratio of the A-group to the B-group.
