Dielectric composition and electronic component

Abstract

Provided is a dielectric composition which includes, as a main component, a complex oxide represented by a general formula AaBbC4O15+α and having a tungsten bronze structure, wherein “A” includes at least Ba, “B” includes at least Zr, “C” includes at least Nb, “a” is 3.05 or higher, and “b” is 1.01 or higher. In the dielectric composition, when the total number of atoms occupying M2 sites in the tungsten bronze structure is set to 1, the proportion of “B” is 0.250 or higher. In addition, in the dielectric composition, an X-ray diffraction peak of a (410) plane of the tungsten bronze structure is splitted into two, and an integrated intensity ratio of an integrated intensity of a high-angle side peak of the X-ray diffraction peak with respect to an integrated intensity of a low-angle side peak of the X-ray diffraction peak is 0.125 or higher.
