A dual-side integrated touch panel structure is provided. The structure comprises a capacitive touch panel and a resistive touch panel. The backs of the touch panels are adhered together via an adhesive layer so the touch panel structure can be used on two sides and operate two functions. Also, to simplify the structure, conductive layers of different functions are disposed on the two sides of the same substrate. This allows the structure to use one less substrate and one less adhesive layer, and keeps the structure thin.
