摘要：
A dielectric ceramic composition includes a base material main component of barium titanate and a subcomponent. A microstructure of the dielectric ceramic composition after sintering includes a first grain having a Ca content of less than 3.5 at % and a second grain having a Ca content of 3.5 to 13.5 at %, and an area ratio of the second grain to an area of the total grains is 70% to 95%.
