Abstract
Electrode portions located on both ends are set to detection electrode portions, ground electrode portions are set on the inside thereof, and a plurality of central electrode portions are set to driving detection portions. A coordinate position of a finger can be obtained based on an output difference between the detection electrode portions, and a vertical distance can be obtained based on an output sum. When the vertical distance of the finger is shorter than a first threshold, switching is performed so that an interval between the detection electrode portions is shortened, and when the finger approaches, a touch detection mode is set.
