Zusammenfassung:A contactless input device includes a plurality of sensor electrodes and a determination unit. The plurality of sensor electrodes are configured to, when a hand performs an operational input over an operating surface of an operating part in a contactless manner, detect individual capacitances correlated to proximity of the hand to the operating surface. The determination unit is configured to calculate sharpnesses of the hand at a plurality of different locations in plan view based on the respective capacitances detected by the plurality of sensor electrodes and determine a location of the operational input based on the sharpnesses.
