Abstract
In a wireless keyboard including an antenna wire for radiating a keyboard output signal from a transmitting section into the air and an electrode sheet secured in a keyboard casing and having an electrically conductive pattern coated thereon, the conductive pattern constituting a part of a switch which is turned on by depressing a key, the antenna wire is formed such that an electrically conductive pattern is coated on the electrode sheet in a manner similar to the electrically conductive pattern constituting a part of the switch. The antenna wire is formed at the same time as the electrically conductive pattern constituting a part of the switch and integrally with the electrode sheet.
