Abstract
A touch keyboard with an improved structure is disclosed. The touch keyboard includes a keyboard casing and an inductive circuit layer. The keyboard casing has a front surface and a rear surface; the front surface has a keyboard key assembly composed of a plurality of touch keyboard keys. The touch keyboard keys are integrally formed with the keyboard casing and projected from the front surface of the keyboard casing. The inductive circuit layer is formed on the rear surface of the keyboard casing and is used to detect touching and sliding operations from the user. The touch keyboard keys are projected from the front surface of the keyboard casing so as to identify positions of the touch keyboard keys without fixing user's eyes on the keyboard and increase touching feeling.
