Abstract
A touch sensor device includes an electrode, which is located at an inner side of a touch panel, and a control unit. The control unit detects a change in a capacitance generated at the electrode when a finger approaches the electrode to determine whether or not the touch panel has been touched from the change in the capacitance. The control unit detects a maximum capacitance generated at the electrode during detection of a touched state and set a first OFF determination threshold value, which is used to detect a non-touched state, to a value that is lower than the maximum capacitance by a predetermined value which is set in advance.
