Abstract
The present invention is directed towards a front cover for a portable electronic device as well as a portable electronic device including such a front cover. The front cover comprises a bottom layer of stiff plastic material having a first opening where at least one input key is to be provided, and a top layer of flexible plastic film that covers the bottom layer including said first opening. These two layers are furthermore bonded to each other. In this way a keypad is provided where dirt cannot enter between keys. The mounting process for the device is furthermore much simplified. It is furthermore possible to produce a waterproof keypad.
