Abstract: A foldable keyboard comprises a keyboard body, a circuit, and a plurality of flexible printed circuit. The keyboard body has a plurality of touch panels in serial connection. Each touch panel has a pair of conductive membranes being segmented into a plurality of blocks for generating a panel signal. The adjacent touch panels are connected by the flexible printed circuits so that the touch panels can be folded in a stacked way. The touch panels are segmented into a plurality of blocks. A plurality of legends is formed on the top surface or the bottom surface of the keyboard body. The legends respectively correspond to the blocks.
