<P>PROBLEM TO BE SOLVED: To provide a capacitive touch panel sensor capable of reducing waviness caused in a film on which transparent electrode patterns are formed. <P>SOLUTION: A touch panel sensor according to the present invention includes: a first film; first transparent electrode patterns formed on the first film; a first adhesive layer laminated on the first film so as to cover the first transparent electrode patterns; a second film laminated on the first adhesive layer; a second adhesive layer laminated on the second film; a third film laminated on the second adhesive layer; and second transparent electrode patterns formed on the third film. Da/Db is 0.5 to 0.9, in which Da is defined as the total thickness of the second film and the second adhesive layer and Db is as the distance between the first transparent electrode patterns and the second transparent electrode patterns. <P>COPYRIGHT: (C)2013,JPO&INPIT |
