Abstract:
An LC composite component with a variable capacitor and an inductor, said component comprising:an electrically insulating substrate having a principal surface on which a stator-side electrode is formed, and having formed thereon a first terminal electrode electrically connected to said stator-side electrode and a second terminal electrode independent of said first terminal electrode;a rotor made of a solid-state dielectric material disposed in contact with said stator-side electrode;a rotor-side electrode supported by said rotor which opposes said stator-side electrode with at least part of said rotor being laid between said stator-side and rotor-side electrodes, thereby forming an electrostatic capacitance;a rotatable support member rotatably secured about an axis line crossing at approximately right angles with the principal surface of said substrate for transmitting its rotation to said rotor, thus making said rotor rotate together therewith, said support member having on its one end side a shape portion for adjustment which is engageable with an adjustment tool;an inductor connected between said first and second terminal electrodes; anda shield cover having an opening for permitting exposure of the adjustment shape portion of said rotatable support member and being attached to said substrate, while housing therein said rotor and said rotatable support member as well as said inductor.
