Abstract:
A dielectric ceramic composition comprising:a main component composed mainly of barium titanate, a first subcomponent including at least one compound selected from MgO, CaO, BaO, SrO and Cr2O3, a second subcomponent containing silicone oxide as a main composition, a third subcomponent including at least one compound selected from V2O5, MoO3, and WO3, a fourth subcomponent including an oxide of R1 (where R1 is at least one element selected from Sc, Er, Tm, Yb, and Lu), and a fifth subcomponent including CaZrO3 or CaO+ZrO2, wherein the ratios of the subcomponents to 100 moles of the main component composed mainly of barium titanate are: the first subcomponent: 0.1 to 3 moles, the second subcomponent: 2 to 10 moles, the third subcomponent: 0.01 to 0.5 moles, the fourth subcomponent: 0.5 to 7 moles (where the number of moles of the fourth subcomponent is the ratio of R1 alone), and the fifth subcomponent: 0
