PURPOSE:To provide a dielectric ceramic composition having a high dielectric constant and a high Q value, in a high frequency region. CONSTITUTION:A compound oxide contains at least Ba, Zn, Nb, W as a metal element. When a composition formula by mol ratio of these metal elements is represented by aBaO.bZnO.cNb2O5.dWO3, a, b, c, d satisfy relations where 0.40<=a<=0.70, 0.10<=b0.35, 0<c<=0.30, 0<d<=0.35, 0.14<=c+d<=0.36, 36, a+b+c+d=1.00. |
