A digitizing tablet that can control the vibration of an operation panel or a support substrate is disclosed. A piezoelectric substrate having a pair of drive electrodes fixed to the front and rear surfaces of the piezoelectric substrate is fixed directly or via one of the drive electrodes to the operation panel or the support substrate. A drive voltage is applied to the pair of drive electrodes after an input as been detected, and the drive voltage causes the expandable piezoelectric substrate to vibrate the operation panel or the support substrate.

Therefore, the vibration energy is not dissipated and there is no time delay in transmission since the operation panel or the support substrate are vibrated directly by the piezoelectric substrate. The expansion and contraction of the piezoelectric substrate can be controlled so that the vibration can be controlled precisely.
