PURPOSE:To obtain a small-size and thin tuning device by containing a capacitor in a recess formed on a placing surface of a printed board, providing a coil on a base from the side to the recess, and connecting the coil and a capacitor electrode to the coil terminal inserted into the base. CONSTITUTION:A coil 11 is wound on a drum core 10, a pot core 9 is coated on the outer periphery, and engaged with threads on the inner surface of a shielding case 8. A chip capacitor 13 which has electrodes at both ends is contained in the recess of the placing surface of the printed board of a terminal base 12. A terminal 14 inserted into the base 12 is projected from the side of the base 12, only the terminal connected with the capacitor 13 is long, bent along the base, and then soldered at 15 to the electrode of the capacitor 13. One end of the terminal is connected with the capacitor 13, and the other portion is disposed vertically on the surface of the board. Then, solder dipping type can be used. Since the coil terminal and the chip capacitor are connected with the same terminal in this manner, the size and the weight can be readily reduced. |
