A multi-layer ceramic dielectric filter contains an external electrode, an internal electrode of the filter, a plurality of cascade schistic ceramic dielectric layers. The external electrode consists of a shield earthing metal electrode and an input and output metal terminal electrode of the filter. The utility model is characterized in that the internal electrode of the filter is coated on the surfaces of each schistic ceramic dielectric layers of the filter. The internal electrode contains a shield earthing electrode, a stripline tapping typed resonator and a capacitor. The utility model uses graphic design in structure, therefore, no hole is needed to be opened when in processing and filters with different frequencies and wide passbands on a same filter volume can be designed with structure optimization on different schistic ceramic dielectric layers by the internal electrode of the filter and effectively promote consistency and reliability of the technology.
