PURPOSE: An element included dielectric filter is provided to minutely control a coupling capacitance and stably mount a communicating means on a PCB(Printed Circuit Board). CONSTITUTION: Dielectric resonators(340¯346) are mounted on a PCB(300) while contacting to lead patterns(310¯313). Communicating means(34a¯34g) electrically communicate inner conducting layers formed at resonance holes of the dielectric resonators with the lead patterns. The communicating means includes a soldering surface contacting to the lead pattern on the PCB(300) and a vertical plate which is extended upward from the soldering surface. Capacitors(370¯380) are mounted on the lead patterns on the PCB(300) and perform coupling operations between the dielectric resonators. Inductors(390,391,392) are mounted on the lead patterns on the PCB(300) and perform coupling operations together with the capacitors.
