There is provided a touch panel which has a simple configuration and which can be accurately and reliably operated. It includes a panel 12 constituting a display screen and an elongated piezoelectric element 16 disposed and secured along each of at least two edges of the panel 12 crossing each other. It includes a pressed position calculating circuit 20 for calculating a position in the panel 12 which has been pressed based on output from the piezoelectric elements 16. It includes a boosting circuit 30 serving as piezoelectric element driving means for applying a voltage to the piezoelectric elements 16 to vibrate them when the pressed position in the panel 12 is calculated by the piezoelectric elements 16 and the pressed position detecting circuit 20.
