To provide an inputting device for performing input by touching a display screen using an indicator, and to solve a problem that the screen may be easily broken caused by increase in usage count and touch of excess strength.

The inputting device has signal applying means 1 for applying an impressed current 5 to a human body, detecting means 2 for detecting a human body impedance 4, and calculating means for calculating input information 8. Durability can be dramatically improved because information can be calculated according to change in values of human body impedance 4 associated with indication of the human body by the indicator, thereby existing no stress to be added to the inputting device itself any more at a time of inputting.
