A dielectric ceramic which comprises a barium titanate composite oxide as the main component, contains at least one rare earth element (R) selected from the group consisting of Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu, and further contains Mg and Ni and in which a crystalline composite oxide comprising the rare earth element (R), Ni, and Ti as major components is present. This dielectric ceramic is used to form dielectric ceramic layers (1a) to (1g). Thus, high reliability can be ensured even when a higher electric field is continuously applied for long in a high-temperature atmosphere.
