Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a touch sensor which highly reliably operates at a low cost. SOLUTION: A touch sensor 10 includes a keyboard having keys K1-K16 defining a touch sensing location, and control circuits associated with the keys K1-K16. The control circuit includes transistors Q1-Q16, and the keys K1-K16 control the transistors Q1-Q16 based on a touch event. A pulse signal generator is connected to the control circuit and generates pulsed signals for transmission to the control circuit. The pulsed signals power the transistors Q1-Q16, and the transistor Q1-Q16 outputs a touch signal when a touch event occurs at the associated key and the transistor Q1-Q16 outputs a non-touch signal when no touch event occurs at the associated key. An analyzer 46 is connected to the control circuit and receives from the transistor Q1-Q16 one of the touch signal indicating the touch event and the non-touch signal indicating the no touch event.
