PROBLEM TO BE SOLVED: To provide a touch switch which suppresses a large-sized display device without making a stain etc. on the screen of the display device.SOLUTION: A proximity sensor 12 is formed of an electrode sheet 16, having a plurality of electrodes 20 formed along a longer direction, wound around, for example, a support member 18 in a spiral shape, in such a manner that the electrodes are positioned on the outer peripheral surface side. At a touch operation by which a finger of a person contacts, a detection unit 14 detects a change of electrostatic capacitance produced on the corresponding electrode of the proximity sensor. Also, the detection unit outputs a touch signal corresponding to the detected touch operation. Here, the width of the proximity sensor is determined by the diameter of the support member, so that a compact proximity sensor is obtained by reducing the diameter of the support member.SELECTED DRAWING: Figure 1

    【課題】表示装置の画面の汚れなどを生じさせることなく表示装置等の大型化を抑えるタッチスイッチを得る。【解決手段】近接センサ12は、長手方向に沿って複数の電極20が形成された電極シート16を、電極が外周面側となるように、例えば支持部材18に螺旋状に巻き付けて形成される。検出部14は、人の指が接触したタッチ操作がなされたとき、近接センサ上で対応する電極に生じる静電容量の変化を検出する。また、検出部は、検出したタッチ操作に応じたタッチ信号を出力する。ここで、近接センサは、幅が支持部材の径により定まり、支持部材の径を小さくすることでコンパクトになる。【選択図】図1
