Claims (1)

[Claims for Utility Model Registration] A product that has a plurality of parallel through holes formed with inner conductors on its inner surface, and one of the surfaces where the through holes open is an open end surface, excluding the open end surface. an outer conductor electrically connected to the inner conductor is formed on the outer surface thereof, and a conductor pattern electrically connected to the inner conductor and insulated from the outer conductor is formed on the open end surface. an insulating tube inserted into two through holes at both ends of the plurality of through holes formed with inner conductors of the dielectric block; an insulating tube inserted into the through hole of the tube from the open end surface side; An input/output terminal consisting of an inserted conductor, a hole or a cutout for the input/output terminal to be inserted through, and a metal case housing the dielectric block, the insulator tube, and the input/output terminal. A dielectric filter characterized in that a portion of the metal case facing the dielectric pattern is partially cut out.
