The utility model relates to structure improvement of a digital capacitance touch pad. The structure of a touch pad comprises a scratch-resistant surface layer and capacitance induction layers which are constructed and bonded into a plate body by a transparent cementing layer, wherein the scratch-resistant surface layer can be a transparent plastic film, the surface of which is hardened; and the capacitance induction layers respectively adopt a structure that a first transparent conducting layer in an X axial direction and a second transparent conducting layer in a Y axial direction are respectively arranged on both sides of a transparent plastic carrier, wherein the two capacitance induction layers are respectively and alternatively arranged in a matrix manner in the plural X axial direction and the plural Y axial direction, so that induction units can be electrically connected with one another in one axial direction, and other induction units can be arranged in an insulating manner in the other axial direct
