Dielectric ceramic layer 0.1 to 0.3 um to such extent m micro 1 the laminated ceramic capacitor as it is difficult and ensure the reliability. A dielectric ceramic of the present invention, is on the superconductor thin film to prevent 100 (Ba 1-x Ca x) m TiO 3 + aMnO+bCuO+cSiO 2 + dMgO+eRO (stage, 100 coefficient, a, b, c, d and e exhibits the molar ratio, m the (Ba 1-x Ca x) of exhibits ratio by mole relative to the amount of to Ti, the RO Y 2 O 3, La 2 O 3, 2CeO 2, Nd 2 O 3, Sm 2 O 3, Eu 2 O 3, Gd 2 O 3, Tb 2 O 3, Dy 2 O 3, Ho 2 O 3, Er 2 O 3, Tm 2 O 3, Yb 2 O 3, Lu 2 O 3 least one selected from rare earth element oxide) as dielectric ceramic which appear as, m of on the superconductor thin film to prevent said, x, a, b, c, d and e the, each, 0.998≤m≤1.030, 0.04≤x≤0.15, 0.01≤a≤5, 0.05≤b≤5, 0.2≤c≤8, 0.05≤d≤3.0, which satisfies the relation 0.05≤e≤2.5, 0.3 micro m or more average particle diameter in addition, is 0.7 micro m hereinafter.
