PURPOSE:To make a device compact, and to reduce production man-hour. CONSTITUTION:The dielectric filter is formed by combining a coaxial resonator in which an outside conductor and an inside conductor are formed at a prismatic dielectric member having a through-hole with a dielectric substrate at which an input and output coupling electrode and a ground conductor are formed. An outside conductor 13 of the coaxial resonator and a ground conductor 23 of the dielectric substrate 21 are electrically and mechanically connected through a coating conductive layer 33 adhered and formed so that the conductive part of the outer peripheral face of a dielectric filter assembly can be coated. |
