Abstract

A dielectric ceramic composition comprising BamTiO2+m (note that "m" satisfies 0. 99 ≤ m ≤ 1.01) and BanZrO2+n (note that "n" satisfies 0. 99 ≤ n ≤ 1.01), an oxide of Mg, an oxide of R (note that R is at least one selected from Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu), an oxide of at least one element selected from Mn, Cr, Co and Fe, and an oxide of at least one element selected from Si, Li, Al, Ge and B. With respect to 100 moles of said BamTiO2+m, 35 to 65 moles of BanZro2+n, 4 to 12 moles of an oxide of Mg, 4 to 15 moles of an oxide of R, 0. 5 to 3 moles of an oxide of Mn, Cr, Co and Fe, and 3 to 9 moles of an oxide of Si, Li, Al Ge and B are included therein.
