20090034157 | CERAMIC LAMINATED DEVICE AND METHOD FOR MANUFACTURING SAME - The present invention relates to a ceramic laminated device including a dielectric ceramic and an Ag electrode. In a dielectric ceramic that can be sintered at low temperatures and has a high dielectric constant and Q value, reactivity between the ceramic and Ag during sintering is suppressed low and segregation of specific elements in the proximity of the electrode is controlled. Thus, a filter having a high Q value and low loss is produced stably. For this purpose, in a ceramic laminated body including at least a ceramic and a Si-containing glass, a ratio of A/B, i.e. a ratio of a Si element concentration (A) within a range at a distance of 5 μm or smaller from the Ag electrode to a Si element concentration (B) within a range at a distance larger than 5 μm from the Ag electrode, is set equal to or smaller than 2. | 02-05-2009 |
