Zusammenfassung:PROBLEM TO BE SOLVED: To provide a protective film of touch panel electrode that has a desired shape and excellent transparency, and also has sufficient antirust performance even if it is a thin film, and a touch panel having such a protective film.SOLUTION: A protective film of touch panel electrode is obtained by curing a predetermined portion of a photosensitive layer composed of a photosensitive resin composition containing a binder polymer, a photopolymerizable compound, and a photopolymerization initiator. For the protective film, heptanonitrile and benzoic acid are detected by pyrolytic gas chromatograph mass analysis.
