A dielectric filter is formed by constituting electrode non-formation parts (4a,4b,5a,5b) opposed as inserting both main surfaces of a dielectric plate (3) as dielectric resonator (45a,45b), as well as by providing two coupling members (10,11) coupled to said dielectric resonator, and a large attenuation quantity required for a certain frequency in a blocking area is secured by generating an attenuation pole in a predetermined frequency area. A dielectric resonator is constituted by providing an electrode (1) on an upper surface of a dielectric plate (3) as a portion thereof being an electrode non-formation part (4a,4b), providing an electrode (2) on a lower surface of the dielectric plate (3) as a portion opposite to the electrode non-formation part (4a,4b) being an electrode non-formation part (5a,5b), and nearly placing probes (6,7) as coupling members (10,11), as well as placing both probes (6,7) in non-parallel. <IMAGE> |
