On the other hand, in the invention described in claim 3, the light emitting paint layer is directly applied to the back surface of the sheet key so as to be integrated, and in the invention described in claim 4, the contact sheet member. Since the light emitting paint layer is applied to the upper surface side of the upper surface film, the number of parts constituting the keyboard is 2, and thus the number of parts can be further reduced.

Further, in the invention according to claim 5, since the base layer made of a single color such as white printing is formed on the back surface side of the light emitting paint layer, light is transmitted through the sheet key. Light reaching the paint layer is prevented from leaking to the back side thereof, and thus the amount of accumulated light in the light emitting paint layer, that is, the amount of light emission is increased, so that the light emitting paint layer can be used more efficiently.

In addition, in the invention described in claim 6, the upper surface film and the lower surface film are interposed between them, and the double-sided adhesive tape is provided with an opening at the portion where the conductive pattern is located. Since they are integrally bonded, the double-sided adhesive tape serves to bond and fix the upper surface film and the lower surface film, and when the key portion of the sheet key is operated, the upper surface film and the lower surface film are separated from each other. Since it has the effect of holding the gap for doing so, it becomes possible to further simplify the structure and reduce the number of parts.
