Abstract
In a detection device, a drive circuit supplies, to a first sensor electrode, a drive signal (second drive signal) of a different frequency in each of multiple detection periods. A detection circuit performs detection of proximity of an object, based on a detection signal (second detection signal) received from a second sensor electrode disposed in the vicinity of the first sensor electrode in each of the multiple detection periods.
