PURPOSE:To adopt the structure offering ease of manufacture, of a small size and easily assembled to a circuit mounted on a printed circuit board. CONSTITUTION:Coupling destination slits 12a,...,12d are formed to a dielectric resonator block 10 having a folded strip line to separate plural dielectric resonators 14a,...,14e while keeping the integrated structure. Outer dielectric bodies 20a, 20b are arranged to both sides of the dielectric resonator block and bonded to them. Independent island shaped electrodes 26a, 26b are formed to an outer circumferential part of the dielectric resonators at both sides to form input/output coupling electrodes. The dielectric resonator block is formed by forming an electrode 18 of a prescribed shape to an outer circumferential part of the dielectric block whose cross section is U-shaped. |
