When the user's finger or other member touches the transparent protective layer 12 of the touch screen 10, an instantaneous capacitance is generated, and the control module 19 detects a change in current so that Coordinates are determined, and corresponding command signals are generated and transmitted to terminal equipment such as a computer.

1 and 3, the transparent substrate 30 is made of a transparent material such as glass or resin, and the whole exhibits an arc-shaped structure, the center portion of which is bent inward slightly. The transparent substrate 30 has a first surface 32 and a second surface 33 facing each other, and a first surface 32 of the transparent substrate 30 that is far from the transparent protective layer 12. Is attached to the touch screen 10.

A translucent metal film 322 is provided on the first surface 32 of the transparent substrate 30, and the metal film 322 is titanium (Ti), nickel (Ni), copper (Cu), and chromium (Cr). Any one of these targets is formed on the transparent substrate 30 by vacuum deposition, sputtering, or plasma jet, and causes the touch type keyboard 100 to have a mirror effect. (mirror effect). In the present embodiment, titanium is preferentially employed due to its excellent wear resistance and corrosion resistance.

The second surface 33 of the transparent substrate 30 is provided with a plurality of key marking portions 34, a driving circuit 36 and a transparent supporting portion 38. In the present embodiment, the key marking portion 34 is formed by spraying or printing a transparent electroluminescent material (Electro Luminescent). The key marker 34 may be designed in English alphabet, Chinese alphabet, Japanese or the like according to demand. The information of the key marker 34 (for example, coordinate range information of the K key and a command signal corresponding thereto) is stored in advance in the control module 19 of the touch screen 10, and the information is stored in the touch screen ( Respectively corresponding to the touched position of 10). The drive circuit 36 is printed around the key mark portion 34 by a transparent conductive material, and the key mark portion 34 is electrically connected to the control module 19 by electric wiring.
