PURPOSE:To provide the manufacture of a dielectric filter for strongly joining a dielectric resonator block and a dielectric substrate by applying glaze on the entire sticking surface, superimposing the dielectric resonator block and the dielectric substrate and baking them at the melting temperature of a silver electrode. CONSTITUTION:The dielectric resonator block 3 for which plural dielectric resonators R1-R3 are integrally formed and the dielectric substrate 5 for which resonator auxiliary circuits such as an inductor and a capacitor, etc., are formed are superimposed by applying the glaze on the entire sticking surface, baked at the melting temperature of the silver electrode and joined. Thus, since the connection silver electrodes are mutually joined with each other by the melting of the silver and the superimposing surface other than the silver electrode is stuck by the glaze, the dielectric resonator block 3 and the dielectric substrate 5 are strongly joined. Then, since the melting temperature of the glaze is below the melting temperature of the silver electrode, when baking is performed at the melting temperature of the silver electrode, the glaze melts as well. |
