Abstract
The present invention is directed to a capacitor apparatus of the capacity variable type. This capacitor apparatus is manufactured by Micro Electro-Mechanical System technology, and comprises an insulating substrate () in which at least two capacitor electrodes (), () are formed on one surface () in the state where they are insulated each other, an actuator () formed by insulating material and having an external shape to bridge over the respective capacitor electrodes (), (), the actuator () being such that a conductor which respectively constitutes capacitors between the conductor () and these capacitor electrodes (), (), and drive means () for allowing this actuator () to undergo an operation to come into contact with one principal surface () of the insulating substrate () or to become away therefrom.
