PROBLEM TO BE SOLVED: To provide superior weather resistances at high temp. load and high humidity load and superior dielectric strength by adding a specified amt. of an SiO2 -TiO2 -MO based oxide sub-component to specified main components and making inner electrodes of Ni or Ni alloy. SOLUTION: A ceramic dielectric layer contains an SiO2 -TiO2 -MO based oxide sub-component (M is Ba, Ca, Sr etc.) about 0.2-3.0wt.% added to a main component given by the formula (Re2 O3 is at least one of Eu2 O3, Gd2 O3 etc., 0.0005<=α<=0.027, 0.002<=β<=0.054, β/α<=5, 1.000<m<1.035). This layer will not may be reduced, even if baked in a reductive atmosphere and inner electorode may be made of Ni or Ni alloy. This reduces the cost and ensures a superior weather resistance and dielectric strength. |
