PROBLEM TO BE SOLVED: To provide a tactile sense presentation device or the like that effectively presents a tactile sense (texture feeling) on a touch panel and allows a user to perform an operation solely by tactile sense without seeing the hand.SOLUTION: The tactile sense presentation device 10 includes a support substrate 11, a plurality of X electrodes 12 and Y electrodes 13 that are parallel with each other and extend on the support substrate, and driving circuits (X electrode driving circuit 14 and Y electrode driving circuit 15). The driving circuit apply a voltage signal of a first frequency to the X electrode corresponding to a target region input from the outside, of the X electrodes, apply a voltage signal of a second frequency to the Y electrode corresponding to the target region, of the Y electrodes, and generate an electric beat vibration in the target region on the basis of the absolute value of the difference between the first and second frequencies. |
