Dielectric ceramics and a multi-layer
ceramic capacitor with internal Ni electrodes having a more improved property showing the reliability such as high accelerated
life time than usual, a temperature characteristic of the
permittivity satisfying the X6S property, and having a
permittivity of from 800 to 1800, wherein the
dielectric ceramics comprise a main ingredient within a range:1.100≦Ba / Ti≦1.7000.02≦a≦0.100.01≦b≦0.05when represented as:ABO3+aRe+bM(in which ABO3 is a general formula for a
perovskite structure, wherein the A cation sites are predominantly occupied by Ba and optionally one or more of Ca and Sr, and wherein the B cation sites are predominantly occupied by Ti and Zr, wherein Re represents at least one
oxide of metals selected from La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y, wherein M is an
oxide of
metal element selected from Mg, Al, Cr, Mn, Fe, Ni, Cu, and Zn, wherein a and b each represents the number of mols for each
oxide based on 1 mol of ABO3 when each oxide is converted into that of a
chemical formula containing one
metal element), and wherein the Zr is within a range, when represented as a ratio of Zr to Ti, of; Ti:Zr=95:5 to 60:40.
