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 panelcomprising a glass substratethat has a sensor unitfor performing detection along the X direction, and a glass substratethat has a sensor unitfor 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.

Projected capacitive touch switch panel

Provided is a capacitive touch switch panel on which it is possible to form a transparent sensor electrode having high quality design shape and reduced reflection of visible light, and which moreover has excellent appearance and ample environmental resistance. This capacitive touch switch panelis provided with a glass substrate, and with a sensor partformed on this glass substrate. The sensor parthas a sensor electrode, this sensor electrodecomprising an Al thin film formed by sputtering or vacuum deposition into a switch configuration on the glass substrateat the opposite surface sidefrom a touch surface, the sensor parthaving an intermediate layer between the glass substrateand at least a portion of the Al thin film. This intermediate layer comprises a thin film that includes at least one metal selected from Cr, Mo, and W.
