Dielectric ceramic composition and ceramic capacitor
A dielectric ceramic composition represented by a general formula {(Na1-v-w-xKvLiwM2x)(Nb1-y-zTayM4z)O3+αMnO+βLa2O3+γLi2O}, wherein 0≤v≤0.01, 0≤w≤0.01, 0.05≤x, z≤0.15, 0≤y≤0.1, 0.003≤α≤0.05, 0.001≤β≤0.05, and 0.005≤γ≤0.05. M2 is Ba, Ca, and/or Sr, and M4 is Zr, Hf, and/or Sn. A ceramic layer is formed of the dielectric ceramic composition, and an internal electrode is formed of a base metal material such as Ni.
