The present invention relates to a touch panel. The touch panel, according to the present invention, comprises: a base material; and an adhesive layer, which is coupled to the base material and comprises an acrylic polymer having 5 to 30 parts by weight of isobornyl (meta) acrylate and 5 to 40 parts by weight of methyl (meta) acrylate, thereby effectively preventing oxygen, moisture, or other foreign substances from infiltrating a base material film and the surface of the adhesive layer or a conductive body thin film and the surface of the adhesive layer, and preventing deterioration of optical properties such as visibility, due to bubbles that are generated form an adhesive surface. In addition, change in resistance of the conductive body thin film is effectively prevented when the adhesive layer is directly coupled to the conductive body thin film and when exposed to extreme conditions, such as high temperature or high temperature and high humidity, thereby enabling stable operation of the touch panel for a long time. |
