Abstract
The keyboard includes a rubber sheet fixed on key tops of a set of key-switch devices. The rubber sheet elastically urges the key tops upward so that they are borne away from the base of the key-switch devices. The rubber sheet is arranged so as to cover the key-switch devices from outside. According to the invention, the cost of a keyboard covered with a dustproof and watertight rubber sheet can be reduced.
