Abstract
A high-frequency coaxial resonator including a tubular dielectric member having a through hole and provided with inner and outer peripheral surfaces and a pair of end surfaces which axially oppose each other. An inner conductor is formed on the inner peripheral surface and an outer conductor is formed on the outer peripheral surface, the outer conductor extending onto one or both end surfaces of the tubular dielectric member so as to approach the inner conductor through a prescribed clearance, thereby forming a capacitance between the inner and outer conductors for adjusting the resonant frequency of the resonator.
