Abstract
A multi-layer ceramic capacitor has a temperature characteristic satisfying an X8R property and has a high specific resistance under a high temperature circumstance, in which the dielectric ceramic composition forming the dielectric ceramics is expressed by a formula: BaTiO+aMgO +bMO+cReO+dSiO, wherein MgO represents MgO conversion, MOrepresents oxide conversion for 1 atom in 1 molecule of at least one metal selected from V, Cr, and Mn, ReOrepresents oxide conversion for 1 atom in 1 molecule of at least one rare earth metal selected from Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Y, and SiOrepresents SiOconversion, and wherein 0.4≦a≦3.0 mol, 0.05≦b≦0.4 mol, 6.0≦c≦16.5 mol, 3.0≦d≦5.0 mol, 2.0≦c/d≦3.3, based on 100 mol of BaTiO.
