Abstract
A detection apparatus is provided and includes detection electrodes; detection circuit configured to be coupled to detection electrodes to detect detection signals corresponding to changes in capacitance of detection electrodes; coupling circuit configured to cause detection electrodes to be a coupled state in which detection electrodes are coupled to detection circuit and non-coupled state in which detection electrodes are uncoupled from detection circuit; drive electrode arranged at a position adjacent to detection electrodes; conductor arranged between detection electrodes and drive electrode; and drive signal generation circuit configured to be coupled to drive electrode to supply drive signal to drive electrode; wherein detection electrodes are provided to one face of insulating substrate, and wherein height of drive electrode from the one face is greater than height of the detection electrodes from the one face.
