In this paper, we propose the touch panel's operation by using human fingernail and finger. And we developed the control circuit that measured coordinates and the electrostatic capacity in the resistive type of touch panel for this realization. In this device, the measurement of coordinates and the electrostatic capacity was possible. In the operation test, the input of fingernail was a tendency to distribute downward from the input of finger, and 90% success area was about 12mm. This operation suits the Fitts' law because the contribution rate is above 0.8 in the operation time and the index of difficulty.
