PURPOSE: To freely realize mounting of chip capacitors between terminals by employing plurality of flat type terminals providing the vertical portion which is inserted into the wiring substrate and the horizontal portion which is exposed at the rear side of terminal block.

CONSTITUTION: The drum type core bobbin 11 winding a coil 12 is fixed by bonding to the terminal block 13 and the variable core 14 is housed in the shield case 15 together with the terminal block 13. The flat terminals 16aW16f fixed to the rear side of terminal block 13 are composed of the vertical portion which is inserted into the wiring substrate (not shown) and the horizontal portion being exposed in the recess 17 provided at the rear side of the terminal block 13, and the extending portion formed inwardly at a right angle is formed at the horizontal portions 16a, 16c and 16d, 16f in both sides among them and the chip capacitor 20 is connected between the horizontal extending portions of the flat terminals 16a, 16c. The groove 18 is provided at the end surface where the terminal block 13 is in contact with the shield case 15 and the lead wire 19 of the coil 12 passes the U-shaped groove 18, is wound around the vertical portion of the flat terminals 16aW16f and is then solder-connected.
