The invention relates to a flexible fabric keyboard, which comprises a key-press layer, a functional layer and an insulating layer, and is characterized in that the functional layer is a three-dimensional flexible fabric woven and formed by insulating yarns and leads continuously; the radial cross section of the fabric adopts a structure composed of support units and hole units woven continuously and alternately, and the hole units are in one-to-one correspondence with key-press positions of the key-press layer; warp-wise leads with rather long floats inside are embedded into the upper layer of the fabric of the hole units to form an array circuit; weft-wise leads with rather long floats inside are embedded into the lower layer of the fabric of the hole units to form a line circuit; and the hole units have the following fabric structure: when any key-press on the key-press layer is pressed, the warp-wise lead on the upper layer of the key-press corresponding to the hole unit will be in contact with the weft-wise lead on the lower layer thereof effectively so as to conduct a keyboard switching circuit; and the support units have the following fabric structure: when any key-press on the key-press layer is released, the support unit adjacent to the hole unit corresponding to the key-press can restore the hole unit and switch off the keyboard switching circuit.
