PROBLEM TO BE SOLVED: To easily and satisfactorily attain connection between a dielectric resonator and a capacitor and to easily and correctly make capacity mutually between plural resonators to a desired value. SOLUTION: Dielectric resonators 1 to 3 are arranged in parallel and a capacitor block 4 is arranged on a same circuit board 5. The connecting conductors 26 to 28 of the capacitor block are soldered directly to the terminal conductor 10 of the resonators 1 to 3. A non-conductor recessed part 30 is provided at the conductors 26 to 28 corresponding to a through hole 13. A separating groove 31 is provided mutually between the conductors 26 to 28.
