摘要： PROBLEM TO BE SOLVED: To obtain a proximity detection device capable of extending a detectable distance enabled to detect the proximity, and at the same time, improving positional resolution of proximity coordinates. SOLUTION: A plurality of detection electrodes are electrically combined in case of detecting an object for detection located at a distance, and a detection electrode combining circuit 5 is provided for separating the plurality of detection electrodes electrically combined, in case of detecting an object for detection located nearby. Capacitances of the detection electrodes electrically combined by the detection electrode combining circuit 5 are detected by a capacitance detection circuit 6, and at the same time, capacitances of the detection electrodes separated are detected by the detection electrode combining circuit 5.
