Abstract
A keyboard covering film including a fabric layer, a transparent layer and a mask layer is disclosed. The transparent layer is disposed on an upper surface of the fabric layer. The mask layer is disposed on a lower surface of the fabric layer. The transparent layer and the fabric layer are treated by a hot pressing process to form a number of keycap receiving sections. The keycap receiving sections, the fabric layer and the mask layer are located on the same side of the transparent layer. The fabric layer and the mask layer have hollow patterns within the keycap receiving sections, wherein the hollow patterns are formed by removing a portion of the fabric layer and the mask layer.
