Disclosed is a transparent electrode sheet which suppresses the precipitation of oligomers without forming a coating layer or an applied layer on the PET surface of the adhesive layer. To avoid heat shrinkage during annealing in the manufacturing process, a touch panel is pre-annealed by heat shrinking the first and second resin films (1, 2) prior to annealing. As a result of having been pre-annealed, when the first and second resin films (1, 2) are heated above glass transition temperature the oligomers within said films are precipitated and disperse. The oligomers, which pass from the resin films (1, 2), along the boundary surface between the films (1, 2) and the adhesive layer (3) and move to the adhesive layer (3), mix with said layer, made from polyethylene containing terephthalic acid and ethylene glycol, and are not precipitated as crystals. Even if the oligomers do not mix with the adhesive layer (3), the light refraction indexes of the oligomers and said layer (3) are almost equal and so the oligomers are not visible. |
