Abstract

The present invention relates to a pad for a touch panel, to a method for manufacturing a touch panel using same, and to a touch panel manufactured by the method. The present invention relates to a pad for a touch panel, comprising: an insulator layer consisting of a transparent organic insulator or an inorganic insulator; an upper transparent conductive material coating layer formed on the upper surface of the insulator layer; an upper metal coating layer formed on the upper surface of the upper transparent conductive material coating layer; and a lower conductive layer formed at the lower surface of the insulator layer, and consisting of: i) a transparent conductive material coating layer, or ii) a metal coating layer, or iii) a stacked layer of a transparent conductive material coating layer and a metal coating layer. The present invention also relates to a method for manufacturing a touch panel using same, and to a touch panel manufactured by the method. Through the above-described configuration, the present invention makes it possible to manufacture a touch panel through processes that are more simplified than conventional processes using a silver paste, and enables easy manufacture and reduces manufacturing costs. Further, the present invention enables the formation of more fine conductive wires at both sides of the touch panel, and can thus achieve a compact device configuration. The present invention minimizes the stepped portion at the edge of the touch panel on which a pattern is formed to prevent defects such as air bubbles in the attached surface of the touch panel when an adhesive layer is attached, thereby achieving a touch panel with a high resolution. The present invention enables the formation of a pattern on the upper surface of the touch panel and the formation of a ground line at the lower surface of the touch panel to be performed at the same time, thereby simplifying the processes.
