Abstract:
A variable-capacitance element includes: a first electrode and a second electrode which are fixed on a substrate with a spacing; a movable electrode; an actuator which is supported on a supporting portion provided on the substrate to drive the movable electrode. The movable electrode is put in an electrically connecting state with the second electrode, when the movable electrode is driven to a first position by the actuator, and the movable electrode is put in an electrically non-connected state with the second electrode, when the movable electrode is driven to a second position by the actuator. The movable electrode is constituted to be always put in an electrically non-connected state with the first electrode.
