Abstract

A touch sensor device (10) includes an electrode (12), which is located at an inner side of a touch panel (11), and a control unit (13). The control unit (13) detects a change in a capacitance generated at the electrode (12) when a finger approaches the electrode (12) to determine whether or not the touch panel (11) has been touched from the change in the capacitance. The control unit (13) detects a maximum capacitance generated at the electrode (12) 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.
