A dielectric ceramic includes ABO3 as a major component and R and M as accessory components, where A is at least one of Ba, Sr and Ca; B is at least one of Ti, Zr and Hf; R is at least one of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and Y; and M is at least one of Ni, Co, Fe, Cr and Mn. The dielectric ceramic contains the components R and M at about 70% or more of analysis points in grain boundaries. This dielectric ceramic is suitable for use in dielectric ceramic layers of a multilayer ceramic capacitor obtained by firing in a reducing atmosphere, has a long life at high temperatures and high voltages, exhibits less time-dependent change in electrostatic capacity under application of a direct-current voltage and has satisfactory reliability even when its thickness is reduced.
