An input device according to a mode of an embodiment includes a detection unit, at least one vibration element, and a vibration control unit. The detection unit detects a contact position of a user on an operation surface. The vibration element vibrates the operation surface. The vibration control unit controls the vibration element in such a manner that a vibration state of the vibration element becomes a first vibration state when the contact position detected by the detection unit is in a predetermined region and that a vibration state of the vibration element becomes a second vibration state different from the first vibration state when the contact position is outside the predetermined region.
