ABSTRACT:
A variable capacitor is provided which is appropriate for suppressing fluctuation in driving voltage characteristic and for achieving a larger variation ratio of static capacitance. The variable capacitor includes a fixed electrode and a movable electrode. The fixed electrode includes a first opposing face, while the movable electrode includes a second opposing face that faces the first opposing face. The movable electrode further includes a curved portion that protrudes toward the fixed electrode. The variable capacitor also includes a dielectric pattern provided on the first opposing face.
