Claim:
1. A touch panel, comprising: a base including an indium tin oxide (ITO) film formed on at least one surface thereof; and a pressure-sensitive adhesive layer directly attached to the ITO film on the base, which comprises an acryl polymer containing 5 to 28 parts by weight of isobornyl acrylate monomer and 5 to 35 parts by weight of methyl acrylate monomer in a polymerized form wherein the acryl polymer has a weight average molecular weight of 750,000 to 2,500,000, wherein the pressure-sensitive adhesive layer has a peel strength with respect to a polycarbonate sheet of 2,500 g/25 mm or more at a peel angle of 180 degrees, a peel rate of 300 mm/min and at room temperature, and a resistance change ratio of the indium tin oxide (ITO) film of 6% or less, wherein the pressure-sensitive adhesive layer completely covers the ITO film, wherein the pressure-sensitive adhesive layer comprises a thiol compound or a thiol polymer derived from an acryl monomer and a thiol compound, and, wherein the thiol compound is at least one of compounds represented by Formulas 2 to 5: where A
