Abstract
A variable capacitive element includes a first fixed electrode and a second fixed electrode that are insulated from each other, a movable electrode arranged to face the first fixed electrode and the second fixed electrode, a dielectric layer provided between the movable electrode and the first fixed electrode as well as the second fixed electrode, a first wiring part for applying a first driving voltage to the first fixed electrode with reference to a potential of the movable electrode, and a second wiring part for applying a second driving voltage to the second fixed electrode with reference to the potential of the movable electrode, the second driving voltage having a polarity different from a polarity of the first driving voltage.
