Abstract
Embodiments of this application disclose a dielectric filter and a communication device. In one example, the dielectric filter includes: a first dielectric block and a second dielectric block that are stacked up, where a first surface of the first dielectric block is opposite to a second surface of the second dielectric block; a first blind hole, a first through hole, and two or more resonance through holes whose openings are located on the first surface of the first dielectric block, and a second through hole whose opening is located on the second surface of the second dielectric block. A metal layer on the first surface of the first dielectric block is connected to a metal layer on the second surface of the second dielectric block.
