Provided is a touch panel. The touch panel includes a base and a pressure-sensitive adhesive layer attached to the base and having a peel strength with respect to a polycarbonate sheet of 1,900 g/25 mm or more. The pressure-sensitive adhesive layer includes an acryl polymer compound containing an acryl polymer and a thiol polymer derived by binding a thiol compound into a chain, or a side chain or terminal end of a chain of the acryl polymer. Accordingly, penetration of oxygen, moisture or other impurities at an interface between the base film and the pressure-sensitive adhesive layer, or at an interface between a conductor thin film and a pressure-sensitive adhesive layer may be effectively inhibited, and degradation in optical properties such as visibility due to bubbles generated at a pressure-sensitive adhesive interface may be prevented. In addition, when the pressure-sensitive adhesive layer is directly attached to the conductor thin film and even exposed to severe conditions such as high temperature or high temperature and high humidity, the change in the resistance of the conductor thin film may be effectively inhibited, and thus the touch panel may be stably driven for a long time.
