Abstract
To provide a projected capacitive touch switch panel having sensor units that are easy to adjust and that minimally reflect visible light, and furthermore having adequate environment-resistance properties. A projected capacitive touch switch panel 1 comprising a glass substrate 2 that has a sensor unit 3 for performing detection along the X direction, and a glass substrate 4 that has a sensor unit 5 for performing detection along the Y direction, in which: the two glass substrates are laminated, and the sensor units are sandwiched between the glass substrates so as to face each other; each of the sensor units has a sensor electrode comprising an Al thin film, and a blackened film including at least one metal selected from Cr, Mo, and W.
