摘要:
A dielectric ceramic composition includes: a base material powder BamTiO3 (0.995≦m≦1.010); 0.2 to 2.0 moles of a first accessory ingredient, an oxide or carbide containing at least one of Ba and Ca, based on 100 moles of the base material powder; a second accessory ingredient, an oxide containing Si or a glass compound containing Si; 0.2 to 1.5 moles of a third accessory ingredient, an oxide containing at least one of Sc, Y, La, Ac, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu, based on 100 moles of the base material powder; and 0.05 to 0.80 mole of a fourth accessory ingredient, an oxide containing at least one of Cr, Mo, W, Mn, Fe, Co, and Ni, based on 100 moles of the base material powder, a content ratio of the first accessory ingredient to the second accessory ingredient being 0.5 to 1.7.
