DIELECTRIC FILTER

PURPOSE:To reduce the number of parts and man-hour of assembling to reduce the cost by coupling first and second filter constituting members to assemble a dielectric filter and cascading dielectric coaxial resonators as their constituting elements by coupling circuit parts of an electrode. CONSTITUTION:A dielectric filter 1 consists of a resonator constituting member 2 as a first filter constituting member to be a part of a dielectric coaxial resonance part, a base substrate 3 as a second filter constituting member to constitute an internal unit, and a cover 4 which protects the side of a surface 31 and ground the case. In this constitution, plural recessed grooves 22 are provided on the surface facing the substrate 3 of the member 2, and conductors 32a to 32c of the electrode provided on the substrate 3 are fitted to these grooves to connect a conductor film 5 provided on side faces of the member to the outer conductor 32a and the inner conductor 32b out of electrode conductors provided on the substrate 3, thereby completing each dielectric coaxial resonator 6 constituting the filter 1. Thus, the resonator 6 and the unit 8 are assembled.
