PROBLEM TO BE SOLVED : To provide dielectric ceramic which is suitable for composing dielectric ceramic layers of a multilayer ceramic capacitor obtained by firing in a reducing atmosphere, and in which temperature dependency on a dielectric constant is not so deteriorated for the thickness even if thin layered, and which has excellent reliability. SOLUTION : The dielectric ceramic has a composition essentially consisting of ABO3(A is Ba or the like, and B is Ti or the like), and comprising rare earth elements and Si. At least a part of the rare earth elements and at least a part of the Si are present as composite compounds 22 including rare earth elements and Si, and different from ABO3particles 21 as the essential components. Also, the composite compounds 22 have a crystallinity at least in a part thereof. COPYRIGHT : (C)2004, JPO |
