PROBLEM TO BE SOLVED: To perform an adjustment without disturbing electrical characteristics, to achieve miniaturization, and to dispense with a hole for adjustment. SOLUTION: A trimmer capacitor 12 is set in the open end side of a through hole in which a central conductor 14 in a coaxial resonator 10 is formed. A thin connection pin 12b is provided at the stator side of the trimmer capacitor 12, and the connection pin 12b is connected to a strip line 21 for connecting input/output terminals. The rotor side of the trimmer capacitor 12 is arranged in the through hole, and an adjustment screw for adjusting the capacity of the trimmer capacitor 12 provided at the rotor side can be rotated by a driver inserted into the through hole from the lower part.
