ABSTRACT:
A production method of a dielectric ceramic composition having a step of firing dielectric material including a main component ingredient and a subcomponent ingredient, wherein said main component ingredient before firing is barium titanate ingredient powder having the perovskite type crystal structure expressed by ABO3, and a ingredient powder having a ratio A/B of A site components and B site components of 1.006≦A/B≦1.035 and the specific surface area of 8 to 50 m2/g is used. According to the invention, a dielectric ceramic composition having preferable electric characteristics and temperature characteristic can be provided even in the case of being composed of fine particle and a capacitor made to be a thin layer.
