ABSTRACT:
A production method of a dielectric ceramic composition using a reacted material obtained by making a main component including barium titanate react with a fourth subcomponent including an oxide of R (note that R is at least one selected from Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu). According to the invention, a dielectric ceramic composition capable of improving the specific permittivity without deteriorating other electric characteristics (for example, a temperature characteristic of the capacitance, insulation resistance, accelerated lifetime of the insulation resistance and dielectric loss), and the production method can be provided.
