The ceramic substrate has a surface thereof having a recess formed therein. The first and second electrodes are provided on the surface of the ceramic substrate so that the recess is located between the first and second electrodes. The component is located over the recess and spaced from the ceramic substrate with a space including the recess. The space including the recess is filled with the resin. The module allows each component to be surface mounted at higher bonding strength, thus preventing short-circuit between the electrodes on the substrate and improving the operation reliability.

摘要： 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.

The compounding ratio of the second component is between 10 wt % and 30 wt % when the sum of the first and second components is 100. In addition, 0.1 to 1 parts by weight of Li2O and 3 to 10 parts by weight of ZnO, relative to 100 parts by weight of the sum of the first and second components, is also contained as a third component.

摘要： A multilayer ceramic substrate includes a glass ceramic body, a conductive pattern, and a via conductor. The conductive pattern is formed in the glass ceramic body and on at least one principal surface of the glass ceramic body. The via conductor makes a connection between the predetermined conductive patterns. The via conductor includes a conductive material and a Mo compound or a Mo metal. The conductive material includes at least one selected from the group consisting of Ag, Au, Pt and Pd as a main component. The amount of Mo compound or Mo metal is in the range of 0.05 to 10 parts by weight in terms of Mo metal with respect to 100 parts by weight of the conductive material. This multilayer ceramic substrate can achieve sufficient flatness and high dimensional accuracy, while preventing defects that occurs in the vicinity of electrodes after firing.
