| 简介 |
A dielectric ceramic composition contains a barium titanate based composite oxide as its main constituent, and contains a first accessory constituent including at least Al and a second accessory constituent including one or more elements selected from among Fe, Co, Ni, Cu, and Zn, wherein the content of the Al is 0.02 to 6 parts by mol with respect to 100 parts by mol of the main constituent, and the content ratio of the second accessory constituent to the Al is 0.01 to 0.4 in terms of mols. Dielectric layers are formed from a sintered body of the dielectric ceramic composition. The addition of various types of accessory elements such as rare-earth elements is possible, if necessary. This invention achieves a dielectric ceramic composition which is capable of ensuring favorable DC bias characteristics while ensuring high reliability, and a laminated ceramic capacitor using the dielectric ceramic composition. |
