PROBLEM TO BE SOLVED: To provide a dielectric ceramic composition having high dielectric constant, large Q-value and excellently stable τf. SOLUTION: The dielectric ceramic composition consists of calcium, titanium, aluminum, tantalum and oxygen and is expressed by a composition formula, aCaO.bTiO2.cAl2O3.dTa2O5 (in the formula, a+b+c+d=1, 0.556<=a<=0.615, 0.154<=b<=0.333, 0.056<=c<=0.1154 and 0.056<=d<=0.1154). |
