Abstract
An input device of the present invention is configured in the following manner: an input part includes electrode parts, which are contactable arranged with facing each other and one of which is to be an operation object, and a pressure-sensitive layer disposed between the electrode parts facing each other; a charge/discharge waveform forming part includes a charge/discharge circuit having a constant current source, a switching element, a capacitor and a resistor, and forms a charge/discharge waveform with a capacitance detection part and a resistance detection part connected; a charge/discharge waveform calculating part detects the change of a capacitance and of a pressure in the input part based on the charge/discharge waveform formed by the charge/discharge waveform forming part, and calculates an operation state, an operation position and an operation pressure.
