Kind Code:

B2

Abstract:

The present invention provides a variable capacitor and a control method thereof capable of responding to applications of electronic apparatus including various electronic devices and communication mobile devices. The electronic device and the communication mobile device including the variable capacitor are provided. A variable capacitor according to the invention includes a pair of electrodes formed so as to sandwich a ferroelectric material layer, in which polarization processing higher than a coercive field in hysteresis characteristics of polarization has been performed to the ferroelectric material layer, and the capacitance can be varied in accordance with a control voltage applied to the electrodes.
