Claim Text:
1. A tactile sense presentation device, comprising: a supporting substrate; a plurality of X-electrodes extended in parallel to each other along a first direction on the supporting substrate; a plurality of Y-electrodes extended in parallel to each other along a second direction on the supporting substrate by being insulated from the X-electrodes; and a driving circuit which applies a first-frequency voltage signal to the X-electrode corresponding to information regarding a target region inputted from outside among the plurality of X-electrodes, and applies a second-frequency voltage signal to the Y-electrode corresponding to information regarding the target region inputted from outside among the plurality of Y-electrodes, wherein: the first and second frequencies are values in which one of the values alone does not present a sense of texture, there is a period where an absolute value of a difference between the first and second frequencies is larger than 10 Hz and less than 1000 Hz, and the driving circuit includes a function which applies a third-frequency voltage signal to an electrode to which the first-frequency voltage signal is not applied among the plurality of X-electrodes and to an electrode to which the second-frequency voltage signal is not applied among the plurality of Y-electrodes.
