Abstract
An electrostatic input device includes a first sensor electrode for input detection, an electronic part, a second sensor electrode for noise detection, the second sensor electrode being placed between the first sensor electrode and the electronic part, and a measurement circuit that measures the capacitance of the first sensor electrode and the capacitance of the second sensor electrode, the measurement circuit calculating the difference between the capacitance of the first sensor electrode and a value obtained by multiplying the capacitance of the second sensor electrode by a constant.
