Claim:
1. A dielectric composition consisting essentially of: 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 containing an amorphous substance containing the A-group and the B-group and a crystalline substance containing the A-group and the B-group, wherein: the inequality 0.5 ≦α≦, 1.5 holds, where a is the molar ratio of the A-group to the B-group in the dielectric composition, the B-group contains Ti in an amount of 0 to 25 mol% with respect to a total amount of Zr and Ti contained in the B-group, and an X-ray diffraction pattern obtained from the dielectric composition using Cu Kαradiation has a peak which is observed in a 2θ range of 30° to 32° having a full width at half maximum of 0.31° to 0.50°, and an electronic device containing a dielectric film formed from said dielectric composition has a dielectric strength of 5.0 MV/cm or more.
