ABSTRACT:
In a MEMS type variable capacity having a piezoelectric driving mechanism, a movable head having movable electrodes are arranged thereon, stationary electrodes is positioned to face the movable electrodes, and a piezoelectric driving beam structure is joined to the movable head and have one end fixed to the substrate. The movable electrode and the stationary electrode form a variable capacity. In the variable capacity, the distance and capacitance between the movable electrode and the stationary electrode of the variable capacity can be maintained constant so as to realize a reproducibility and a reliable controllability.
