Patent ID: 7262146

Claim:
A dielectric ceramic composition, comprising: a main component including barium titanate; a first subcomponent including at least one of MgO, CaO, BaO and SrO; a second subcomponent functioning as a sintering auxiliary agent; a third subcomponent including at least one of V 2 O 5 , MoO 3 and WO 3 ; a fourth subcomponent including an oxide of R1, where R1 is one of more elements each selected from a group consisting of Sc, Er, Tm, Yb, and Lu; a fifth subcomponent including CaZrO 3 or CaO+ZrO 2 ; and an eighth subcomponent including an oxide of A, wherein A is one or more elements each selected from a cation element group consisting of Al, Cr, Ga, and Ge, where each of the elements has an effective ionic radius at the time of 6 coordination of 0.065 nm to 0.085 nm; and a ratio of said eighth subcomponent with respect to 100 moles of said main component is greater than 1 mole and less than 4 moles.
