Abstract
An electrostatic input device includes: a plurality of first detection electrodes that are configured to detect approach of an object within a first distance from a detection face; a second detection electrode that is provided between the plurality of first detection electrodes and configured to detect approach of the object within a second distance from the detection face, where the second distance is longer than the first distance; and a detection circuit that is configured to detect change in capacitance of the plurality of first detection electrodes and the second detection electrode.
