摘要：
There is provided a dielectric ceramic composition including a base powder, wherein the base powder includes: a first major component represented by BaTiO3, a second major component represented by (Na, K)NbO3, and a third major component represented by (Bi, Na)TiO3. The base powder is represented by xBaTiO3-y(Na, K)NbO3-z(Bi, Na)TiO3, where x+y+z=1, and x, y, and z are represented by mol, and x, y and z satisfy 0.5≦x≦0.97, 0.01≦y≦0.48, and 0.02≦z≦0.2, respectively. In certain embodiments, the base powder is be represented by xBaTiO3-y(Na0.5K0.5)NbO3-z(Bi0.5Na0.5)TiO3.
