Claims

[Scope of utility model registration request]

In a dielectric filter having a conductor inside a dielectric,
A dielectric made of ceramics or the like is formed into a substantially elliptical cylinder shape, a central conductor of the dielectric is formed into a flat plate, and the dielectric is placed horizontally so that its flat surfaces are up and down. A dielectric filter characterized in that a capacitance electrode is attached to the lid body so as to adjust a gap between the lid body and the flat upper surface of the dielectric body.
