Abstract: Provided is a touch sensor having a simple structure and enabling a driver to appropriately and quickly manipulate the touch sensor as intended without looking at a manipulation surface of the touch sensor. The touch sensor includes: multiple electrodes; detection means for detecting touch on any of electrodes and for outputting a detection signal for each electrode; touch judgment means for judging whether each of the electrodes is touched or untouched based on the detection signal; a switch having a manipulation button; control mode judgment means for determining a control function for a controlled device in accordance with an input signal transmitted from the switch when the manipulation button is manipulated; and permission means for permitting the touch judgment means to judge touch on each electrode in response to the input signal from the switch.
