<p>PROBLEM TO BE SOLVED: To provide a touch panel that hardly causes warpage, even if it is exposed to severe temperature environment or humidity environment. SOLUTION: A pair of upper electrode sheet 1 and a lower electrode sheet 2, each having transparent electrodes are arranged facing each other on a transparent film formed of polyethylene terephthalate interposing spacers 3 between the electrodes, and a transparent holding plate 5 formed of a polycarbonate plate is bonded to the entire undersurface of the lower electrode sheet 2 via a transparent bonding layer 4. Additionally, a transparent warpage correcting sheet 6 formed of a polyethylene terephthalate film is bonded to the entire undersurface of the transparent holding plate 5 via a transparent bonding layer 4.</p> |
