Abstract
Provided is a touch panel apparatus capable of easily setting a touch sense produced by oscillatory waves of plural piezoelectric elements according to a user'"'"'s taste. To this end, a touch sense pattern table (51) stores a plurality of touch sense pattern values made up of plural parameter values of a voltage table (52), plural parameter values of a frequency table (53), and plural parameter values of a phase difference table (54). A vibration diving control part (18) applies a driving signal to the piezoelectric elements of first to third groups to vibrate the touch panel (12) based on the parameter values acquired from the voltage table (52), the parameter values acquired from the frequency table (53), and the parameter values acquired from the phase difference table (54), correspondingly to the plurality of the touch sense patterns stored in the touch sense pattern table 51.
