Abstract:
A dielectric ceramic composition contains dielectric particles containing a main component represented by a composition formula (Ba1-x-ySrxCay)m(Ti1-zZrz)O3 and grain boundaries present between the dielectric particles. The values of m, x, y, and z in the composition formula are all molar ratios. In the composition formula, 0.9≤m≤1.4, 0≤x
