PROBLEM TO BE SOLVED: To connect a terminal formed on an EL element to an external power source without using a separate member such as a connector. SOLUTION: This cover member 1 for a push-button switch is provided with: a key sheet 10 composed by integrally molding a key top 11, a base material film 12 and an ornamental layer 13; and an EL sheet 20 composed by integrally molding a base material film 21, a transparent electrode 22, a luminescent layer 23, a dielectric layer 24 and a counter electrode 25. An insulation layer 33 is formed on the counter electrode 25 side of the EL sheet 20, and terminal parts 32 for connecting them to the external power source are respectively formed at one-side ends of the transparent electrode 22 and the counter electrode 25. The key sheet 10 and the EL sheet 20 are stuck to each other by an adhesive layer 31. The adhesive layer 31 is formed only in partial areas of contact surfaces of the key sheet 10 and the EL sheet 20. COPYRIGHT: (C)2007,JPO&INPIT
