Abstract
A capacitive sensor includes: a first sensing electrode connected to a first reference capacitor in which is stored reference electric charge; a second sensing electrode connected to a second reference capacitor in which is stored reference electric charge; and a shield electrode to which is applied electric potential equal to that of the first sensing electrode and the second sensing electrode. The first sensing electrode positions adjacent to a detecting surface of the capacitive sensor, and the second sensing electrode positions opposite to the detecting surface in such a manner that the first and second sensing electrodes are spaced apart and facing to each other. The shield electrode is configured to partly expose the first and second sensing electrodes on the side of the detecting surface, and the shield electrode extends toward the detecting surface beyond the first sensing electrode.
