Patent ID: 7396791

Claim:
A dielectric ceramic composition, comprising a main component including Ba, Ca and Ti and having a perovskite crystal structure expressed by a general formula ABO 3 , and a fourth subcomponent including a compound of Zr; and a fifth subcomponent including at least one compound selected from the group consisting of V 2 O 5 , MoO 3 and WO 3 ; wherein a content of said fourth subcomponent with respect to 100 moles of said main component is larger than 0 mole and smaller than 5 moles in terms of Zr; wherein a content of said fifth subcomponent with respect to 100 moles of said main component is 0.01 to 0.2 mole, and a C.V. value of a distribution of Zr element calculated by formula (1) from standard deviation σ of detection strength and an average detection strength x of the Zr element distribution in said dielectric ceramic composition is 100 or lower; wherein formula (1) is: C.V. value=(standard deviation σ of detection strength/an average detection strength x )×100.
