A keyboard touch electrode module includes a plurality of same electrode matrices, which are arranged along a lengthwise direction and a widthwise direction and formed by a plurality of series of first electrodes and a plurality of series of second electrodes which interlace with each other. Adjacent two of the electrode matrices in the widthwise direction are mis-aligned. The electrode matrices thereon define a plurality of key projection areas, each of which covers a same key-face electrode pattern. A touch keyboard includes a base, a plurality of keycaps, a plurality of supporting structures connected to and between the base and the keycaps, and the keyboard touch electrode module disposed between the base and the keycaps. The keyboard touch electrode module can senses a non-pressing movement on the keycaps.
