Abstract: The present invention provides a transparent touch pad and a method for manufacturing the same. The transparent touch pad includes a first transparent substrate, a second transparent substrate and an adhesion layer. The adhesion sides of the first transparent substrate and the second transparent substrate are respectively provided with a plurality of first sensing conductors and second sensing conductors and are adhered by the adhesion layer to form a transparent touch pad having two-dimensional arrangement of sensing conductors.

In this way, the structure of the touch pad is simplified and the production cost is reduced.
