Patent ID: 7399724

Claim:
A production method of a dielectric ceramic composition for producing a dielectric ceramic composition comprising a main component including barium titanate and a fourth subcomponent including an oxide of R, wherein R is at least one selected from the group consisting of Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Th, Dy, Ho, Er, Tm, Yb and Lu, comprising the steps of: preparing a reacted material obtained by making the material of the main component react with a part of the material of the fourth subcomponent to be included in the dielectric ceramic composition; and adding remaining material of the fourth subcomponent to be included in the dielectric ceramic composition to the reacted material, wherein a content of the fourth subcomponent to be brought to react with a material of the main component in advance is 0.01 to 0.2 mole in terms of R with respect to 100 moles of the main component.
