Abstract
A key unit includes a reinforcing plate having a support frame for surrounding and supporting key groups arrayed on a key-operating surface of the key unit. The support frame is formed at least by processing the outer edge of the reinforcing plate, and the key unit is installable to a mobile device directly from an outside of a casing of the mobile device through the support frame, for example, by fitting the support frame into an opening provided on the casing of the mobile device into which the key unit should be incorporated. For a decoration to the support frame or an exposed part of the reinforcing plate, there are used printing, painting, or various film-forming methods with a metal or a nonmetal.
