Abstract:
A touch switch structure is provided that can be preferably used for an automotive instrument panel and can securely prevent misjudgments and incorrect detections with respect to operations on the switch. For that purpose, the touch switch structure comprises a base material 2 made of a nonconductive material; a shield electrode layer 4 made of a conductive material and formed on one surface of the base material 2; a touch detection electrode 3 formed on one surface of the base material 2 at the portion where the shield electrode layer 4 is not formed; and an insulation layer 5 made of a nonconductive material and formed at least between the shield electrode layer 4 and a connection pattern 6 of the touch detection electrode 3.
