ABSTRACT:
A production method of a dielectric ceramic composition at least including a main component including a dielectric oxide having perovskite-type crystal structure expressed by a formula ABO3(note that in the formula, “A” indicates one or more elements selected from Ba, Ca, Sr and Mg, and that “B” indicates one or more elements selected from Ti, Zr and Hf) comprises steps of preparing a main component material including said dielectric oxide expressed by ABO3; preparing a subcomponent material including a composite oxide expressed by M4R6O(SiO4)6(note that “M” indicates at least one selected from Ca and Sr, and that “R” indicates at least one selected from Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu); mixing said main component material and subcomponent material to obtain a dielectric ceramic composition material; and firing said dielectric ceramic composition material.
