PROBLEM TO BE SOLVED: To provide an IC card which realizes a plurality of functions by using a pressure sensor as a switch.SOLUTION: An IC card 1 is provided with, as its switch, a pressure sensor 10 using a film type sensor. An electrode 11 of the pressure sensor 10 deflects as a switch button 4 arranged above the pressure sensor 10 is pressed down, and a contact area between the electrode 11 and a carbon sheet 15 varies depending on a pressure while being pressed down, resulting in variation of voltage inputted from a power supply 25 to a control part 20 via the pressure sensor 10. On the IC card 1, if the switch button 4 is weakly pressed down and an input voltage to the control part 20 is continuously within a range v1 for a time t or more, the control part 20 is activated and performs display of an initial display data on a display 3, and later if the switch button 4 is strongly pressed down and an input voltage to the control part 20 is continuously within a range v2 for a time t or more, it changes display of the display 3 to different data. |
