Provided is a liquid control device that can, with a compact device configuration, adjust an
electric field, a
magnetic field, an
electromagnetic field, or an electromagnetic wave which is generated from electrodes, and perform an effective therapy or treatment. A liquid control device according to one embodiment of the present invention is provided with at least one
electrode and a controller that controls at least one of the
voltage value, the current value, the frequency, or the phase of a
voltage or a current to be applied to the
electrode. The liquid control device is characterized in that, in a state where the
electrode is disposed so as to face an object unit, the controller adjusts the
voltage value, the current value, the frequency, or the phase of the voltage or the current which is to be applied to the electrode, controls an
electric field, a
magnetic field, an
electromagnetic field, or an electromagnetic wave which is generated from the electrode, and, in accordance with the object unit which faces the electrode, performs control on at least one of the output direction of the
electric field, the
magnetic field, the
electromagnetic field, or the electromagnetic wave which is generated from the electrode, and the frequency and the voltage which are applied to the electrode so as to vary over time, or control on the duration in which the voltage is applied to the electrode.
