A dielectric filter is provided to manufacture a conductive film in an upper surface of a dielectric block through a simple strip process by forming a coupling control bar in a bar-shaped groove. A dielectric filter includes a dielectric block(10), a first terminal(P1), and a second terminal(P2). The dielectric block is equipped with a first resonator(R1), a second resonator(R2), and a third resonator(R3). The first terminal is extended from a left-side surface of the dielectric block to a front surface(12). The second terminal is extendedly formed from a right-side surface(13) of the dielectric block to the front surface. The first terminal is extended from the left-side surface of the dielectric and extendedly formed to the front of the dielectric block via a notch resonator(Rn1), reaching the second resonator. |
