[PROBLEMS] To reduce the occurrence of burrs and cracks on a cut end face even with a brittle film that is easily torn, and to prevent the end face from cracking or sagging due to edge standing when wound into a roll. A resin film excellent in productivity stability in this step, particularly suitable for optical applications such as a polarizer protective film, and a method for producing the same. A resin film roll in which a resin film having a raised portion of a cut portion at 5 μm to 30 μm at both ends in the width direction and a protective film having a width smaller than that of the resin film laminated at least on one side thereof are wound up.
