The embodiment of the invention provides a dielectric filter, which relates to the technical field of communication device components, and provides a new cross coupling medium filter structure. Dielectric filter provided by the embodiment of the invention comprises at least three dielectric resonator, each resonant cavity including debugging hole, debugging holes in the body, each hole and around the debugging form a resonant cavity; a blind hole is included between 22 adjacent cavities, holes are used to realize the cross coupling. The dielectric resonator provided by the embodiment of the invention simplifies the structure of capacitive coupling and makes the structure more miniaturized.
