| 内容： | A dielectric ceramic composition for high frequencies of Patent Document 1 has a firing temperature of as high as 1350 DEG C. to 1400 DEG C. and is unsuitable for use as a material for multilayer capacitors because of its excessively high firing temperature. A multilayer capacitor of Patent Document 2 requires a complicated time-consuming manufacturing process and may cause a structural defect due to a difference between the coefficients of thermal shrinkage of an adhesive layer and a ceramic layer, thereby causing difficulty in miniaturization and multilayering of a multilayer ceramic capacitor. |
