摘要:
A dielectric ceramic composition including a dielectric base phase containing BaTiO3 as a main component, and plate-shaped or acicula deposition phase existing together in the dielectric base phase. Preferably, the dielectric ceramic composition includes a main component of BaTiO3, a first subcomponent including at least one compound selected from MgO, CaG, BaG, SrO and Cr2O3, a second subcomponent of (Ba, Ca)xSiO2+x (where, x=0.8 to 1.2), a third subcomponent including at least one compound selected from V2O5, MoO3, and WO3, and a fourth subcomponent including an oxide of R1 (where R1 is at least one element selected from Sc, Er, Tm, Yb, and Lu), a fifth subcomponent including an oxide of R2 (where R2 is at least one element selected from Y, Dy, Ho, Tb, Gb and Eu), wherein the ratios of the subcomponents to 100 moles of the main component of BaTiO3 are first subcomponent of 0.1 to 3 moles, second subcomponent of 2 to 10 moles, third subcomponent of 0.01 to 0.5 mole, fourth subcomponent of 0.5 to 7 moles, and fifth subcomponent of 2 to 9 moles (where the number of moles of the fourth and fifth subcomponents are respectively the ratio of R1 and R2 alone).
