PROBLEM TO BE SOLVED: To provide an electrostatic capacitance type touch switch that is reduced in overall size by superposing the switch part of the touch switch and the antenna of a non-contact IC card while preventing the touch switch from adversely affecting the performance of the antenna.SOLUTION: An action to perform a touch switch mode in which outputs from the antenna of a reader/writer of a non-contact IC card are stopped and the ground line of a touch switch is grounded to detect inputting with an inputting object such as a human finger or a touch pen and a non-contact IC card mode in which outputting is done from the antenna of the reader/writer of the non-contact IC card, the ground line of the touch switch is placed in a floating state and all the electrostatic capacitance switch electrodes are placed in a floating state are alternately repeated at least once for each mode. |
