<P>PROBLEM TO BE SOLVED: To provide a touch panel sensor with which unevenness of interference can be reduced. <P>SOLUTION: A touch panel sensor of the present invention comprises: a film base material; a first transparent electrode pattern formed on a first face of the film base material; a first adhesive layer laminated on the first face of the film base material so as to cover the first transparent electrode pattern; a second transparent electrode pattern formed on a second face of the film base material; and a second adhesive layer laminated on the second face of the film base material so as to cover the second transparent electrode pattern. The film base material has an in-plane phase difference of λ/4 with respect to a wavelength λ in the visible light region. <P>COPYRIGHT: (C)2013,JPO&INPIT |
