Document Type and Number:
WIPO Patent Application WO/2019/187405
Kind Code:
A detection device provided with a plurality of detection electrodes the detection purposes of which are different from each other, wherein it is made possible to suppress a reduction in detection capability while suppressing an increase in the size of the detection device. [Solution] This detection device is provided with an upper detection electrode, a lower detection electrode provided by superimposition on the underside of the upper detection electrode, a proximity state detection means for detecting the proximity state of a detection object to a detection surface on the basis of a change of capacitance of one or both of the upper detection electrode and the lower detection electrode, and a switching means capable of switching the upper detection electrode and the lower detection electrode between a first state in which the electrodes are mutually insulated and a second state in which the electrodes are mutually shorted.
