Dielectric ceramic and process for producing the same.

摘要

A dielectric ceramic essentially consisting of a compound having a disordered perovskite-type complex crystal structure and having a composition represented by the general formula (I): BaxAyBl-x-yOw (I) (I) where A represents at least one element selected from the group consisting of Zn, Ni, Co and Mg, and the Mg content in the A is not more than 0.44y; B is at least one element selected from the group consisting of Ta and Nb; x and y are a number of 0.49
