Abstract:
1. A dielectric filter comprising: a dielectric block having therein resonator holes extending between a first surface of the dielectric block and a second surface opposite to the first surface, the resonator holes being arranged in parallel and having internal conductors formed on internal surfaces of the resonator holes; external conductors formed on surfaces of the dielectric block, the first surface of the dielectric block being used as an open circuit surface; and a conductive cover for covering the open circuit surface of the dielectric block, wherein said conductive cover has a bent portion which defines a first part and a second part, said first part being placed in contact with one of the external conductors and said second part being arranged parallel to the open circuit surface, and said conductive cover has at least one inwardly projecting portion at a predetermined position along the bent portion.
