The invention discloses a touch keyboard. The touch keyboard comprises a connection module which is used for connecting a computer, a keyboard base and keys, wherein the keys comprise a key housing, a first electrode, a piezoelectric element, a second electrode and a key base plate, the key base plate is connected to the keyboard base, the key housing is connected to the first electrode, the piezoelectric element is arranged between the first electrode and the second electrode, there is no acting force contact or critical contact of the first electrode with the upper surface of the piezoelectric element, and there is no acting force contact or critical contact of the second electrode with the lower surface of the piezoelectric element. As can be seen, electric charges can be generated when the piezoelectric element is squeezed, at the moment a user presses the keys, the piezoelectric element can generate corresponding charges under the pressure exerted by the user, the computer can then sensitively judge an input action made by the user, while when a traditional keyboard is utilized to input, the user needs to thoroughly press the keys to the bottom before the computer judges the input action made by the user. Therefore, the input sensitivity of the touch keyboard is obviously higher than that of the traditional keyboard.
