Abstract: Disclosed is a thin key sheet in which the adhesive is prevented from being squeezed out and in which adhesive marks and bubble marks are hard to be visible. An adhesive layer is in a dot pattern formed by a plurality of dots spaced apart from each other by gaps, so when attaching a key top and a base sheet to each other through an intermediation of the adhesive layer, it is possible to allow air to escape through the gaps, and bubbles recognizable to a naked eye are not easily trapped by the interior of the adhesion layer or an interface between the adhesive layer and the key top. Further, since the adhesive layer is a screen print layer, a dimension of elements of fine pattern thereof can be on an order of microns, thereby making the fine pattern of the adhesive layer hard to be visible through the key top.
