Abstract:
1. A dielectric ceramic composition comprising at least a main component containing a dielectric oxide of a composition expressed by {(Sr a first subcomponent containing at least one type of compound selected from oxides of V, Nb, W, Ta, and Mo and/or compounds forming these oxides after firing, wherein the symbols m, x, and y showing the molar ratio of the composition in the formula contained in the main component are in relations of 0.94<m<1.08, 0≦x≦1.00, and 0≦y≦0.20 and the ratio of the first subcomponent with respect to 100 moles of the main component, which is converted to the metal element in the oxide, is 0.01 mole≦first subcomponent<2 moles, and wherein the dielectric ceramic composition is obtained by performing heat treatment in an atmosphere having an oxygen partial pressure of 10
