<p><P>PROBLEM TO BE SOLVED: To provide a touch panel excellent in preventing Newton's rings when the touch panel is pressed with good durability of a conductive film. <P>SOLUTION: In the touch panel 7, conductive films Da and Db of a pair of panel plates Pa and Pb having the conductive films Da and Db face to each other via a spacer S and the touch panel is of a resistance film system in which the panel Pa on the pressed side is provided at least with a base material (A)1, an adhesive layer 2, a base material (B)3, and the conductive film Da in this order. The conductive films Da and Db of the pair of panel plates Pa and/or Pb are provided on a Newton's rings preventive layer 4 whose Arithmetic Mean Deviation of the Profile (Ra) in JIS B0601:1994 is 0.07μm to 0.3μm and whose maximum height (Ry) is 1.5μm to 2.0μm. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
