A ceramic multilayer substrate includes a plurality of ceramic substrates being stacked vertically, each substrate having a designated thickness; pattern layers formed on surfaces of the ceramic substrates so as to form circuit elements; external terminal vertically formed on side surfaces of the stacked ceramic substrates; and internal connection parts, each of which is formed on a part of one of the pattern layers, is connected to one of the external terminals so as to exchange signals with the outside, and is broad enough to surround at least partially the connected external terminal.

Ceramic multilayer substrate

A dielectric filter is disclosed in which an open area without being spread with a conductive material is formed on the rear face of a dielectric block with a conductive material spread thereon, thereby making it possible to improve the filtering characteristics of the filter and to miniaturize the filter. That is, coupling capacitances and coupling inductances are formed between resonance holes of the rear face of the dielectric block. Further, conductor patterns are formed on the front face of the dielectric block so that coupling capacitances are formed between the resonance holes of the front face, and that loading capacitances are provided to the respective resonance holes.
