PROBLEM TO BE SOLVED : To provide a laminated ceramic capacitor having a temperature characteristic which satisfies X8R characteristic and having high specific resistance under a high temperature circumstance and to provide dielectric ceramic constituting it. SOLUTION : The dielectric ceramic whose formula is denoted as (Bi0.5Na0.5)xBa1-xTiO3 and whose main component is a compound having an x value of 0.05-0.2 is characterized by containing at least one kind of rare earth metals selected from among Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Y as a first auxiliary component by 0.25-1.50 mol based on 100 mol of the main component, Mg by 0.20-1.50 mol based on 100 mol of the main component and at least one kind of metals selected from among V, Cr and Mn by 0.03-0.60 mol based on 100 mol of the main component.
