Abstract
A coaxial resonator which can be electrically connected to an inductance or similar electric element easily to reduce the number of work steps for mounting and the number of parts, and a dielectric filter and a dielectric duplexer which include a resonator and which can be more compact and installed in a diminished space. The coaxial resonator includes a dielectric block having a through-bore extending through opposite end faces thereof, and a conductor layer formed over an outer peripheral surface of the block except one end face thereof and over a block inner surface defining the through-bore for causing electromagnetic waves to resonate within the dielectric block. A lead-equipped electric element has its lead inserted in and fixed in the through-bore and electrically connected to the conductor layer over the bore-defining inner surface with a braze filler metal or electrically conductive adhesive.
