Zusammenfassung:PROBLEM TO BE SOLVED: To provide a reflectively backed photosensitive element which reduces small defects, enhances production yield in patterning process and in subsequent process of the reflectively backed photosensitive resin layer, and improves reliability of parts. SOLUTION: In the reflectively backed photosensitive element obtained by successively stacking (a) a ruggedness forming layer support film, (b) a reflectively backed photosensitive resin layer and (c) a protective film, the protective film (c) consists essentially of acrylic polymer.
