Abstract: An input device and a driving device able to be made thin and secure sufficiently large vibration amplitude are provided. The input device comprises an input panel, a current conducting element for conducting a driving current, and a magnetic field application unit for applying a magnetic field on the current conducting element. Both of the current conducting element and the magnetic field application unit are arranged in the peripheral region of the input panel. The magnetic field applied by the magnetic field application unit is parallel to the input panel and intersects the current conducting element. When the input panel is touched, a driving current is fed into the current conducting element, and a force is imposed on the current conducting element and the magnetic field application unit, making them move. This movement further drives the input panel to vibrate. Consequently, input operations can be recognized by feeling the vibration of the input panel.
