PURPOSE:To mount the dielectric filter onto a main board with one mount, to simplify the manufacture process of the dielectric filter, to reduce man-hours and to make the device using the dielectric filter small in size by eliminating the parts in duplicate. CONSTITUTION:A circuit pattern 2 required for the circuit of a device is formed on a main board 1 at the device side. After a connection conductor 3 in response to an inductance Lf required for the dielectric filter and number of resonators is formed, electric components (Lm and Cm or the like) are soldered to the circuit pattern 2 required for the device and a chip capacitor CC is soldered to the connection conductor pattern 3 and a contact pin 4 is soldered on each connection conductor pattern 3. After the resonator 5 is inserted to the contact pin 4 rising from the connection conductor pattern 3 and soldered and a shield case 16 is covered to make the filter complete. |
