Claims

[Scope of utility model registration request]

At least two through conductive portions are formed at a predetermined interval in the direction of two opposing surfaces of the dielectric base, and a conductive film is coated on the outer and inner surfaces of the dielectric base except for one surface. and a dielectric resonator portion formed between each of the through conductive parts and the conductive film is coupled by a capacitor formed between the through conductive parts, and this is capacitively coupled to an external circuit. A partially exposed portion of the dielectric substrate not coated with a conductive film is formed on one outer surface parallel to the two conductive through parts, and two surfaces on which the ends of the conductive through parts are located. A dielectric filter characterized in that an electrode in contact with the ridgeline portion of the dielectric substrate exposed portion and an electrode in contact with the through conductive portion of 2a are formed on one inner surface of the dielectric filter so as to face each other.
