Abstract
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 panel 1 is provided with a glass substrate 2, and with a sensor part 3 formed on this glass substrate 2. The sensor part 3 has a sensor electrode 4, this sensor electrode 4 comprising an Al thin film formed by sputtering or vacuum deposition into a switch configuration on the glass substrate 2 at the opposite surface side 2b from a touch surface 2a, the sensor part 3 having an intermediate layer between the glass substrate 2 and 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.
