Abstract

There are provided a dielectric filter with excellent electrical characteristics, a duplexer, and a communication device using the dielectric filter. A dielectric filter includes a dielectric block provided with first through holes; inner conductors disposed on inner surfaces of the first through holes; second through holes; a terminal electrode connected to an inner conductor located at on end; a terminal electrode connected to an inner conductor located at the other end; and an outer conductor surrounding the dielectric block, being connected to a reference potential, wherein the first through holes are located on a second main surface side, and the second through holes are located on a first main surface side with respect to the first through holes. A duplexer and a communication device use this dielectric filter.
