<p>Disclosed is a highly reliable touch panel sensor comprising a guiding wiring that is less likely to cause an increase in electrical resistance and disconnection with the elapse of time, has a low electrical resistance, can ensure electrical conduction to a transparent conductive film, and can be connected directly to the transparent conductive film. The touch panel sensor comprises a transparent conductive film and a guiding wiring made of an aluminum alloy film connected directly to the transparent conductive film. The aluminum alloy film comprises 0.2 to 10 atomic% in total of at least one element selected from an X group consisting of Ni and Co. The aluminum alloy film has a hardness of 2 to 15 GPa.</p> |
