To inexpensively provide a dielectric coaxial resonant component with which the number of parts is reduced, electromagnetic field leakage can be prevented and mountability is improved by providing an outer conductor in contact with an inner conductor on one end face and one input/output electrode formed while being insulated from the outer conductor at one part in the forming area of outer conductor over all the outer peripheral surface including both end faces of dielectric block.
The outer conductor is formed over all the outer peripheral surface including both end faces 3a and 3b of dielectric block 2 and this outer conductor is respectively in contact with the inner conductor on the end face 3a and the inner conductor on the end face 3b. One input/output electrode 6 is formed inside the forming area of outer conductor. This input/output electrode 6 is formed while being insulated with the outer conductor, and formed over side faces from the mounting plane of dielectric block 2. Thus, since the functions of the inductor and capacitor or the like can be added to one dielectric block 2, the number of parts for consisting the dielectric coaxial resonance component can be reduced.
