Abstract
A dielectric ceramic material is composed of a perovskite compound represented by ABOas a main component. In the case where ABOis, for example, BaTiO, the crystal grains include BaTiOcrystal grains composed of the main component and, as secondary phases, Mg—Ni—Ti-containing crystalline grains composed of a crystalline oxide containing at least Mg, Ni, and Ti and Ba—Si-containing crystalline grains composed of a crystalline oxide containing at least Ba and Si.
