To provide a film roll that suppresses formation of a deformed part caused when a long-sized film is wound around a winding core part, and a method of manufacturing the same.

There are provided the film roll 1 which includes a cylindrical or columnar winding core part 2 and a long-sized film 3 wound in a roll shape around an outer circumferential surface 2a of the winding core part 2, and further includes an elastic member 4 arranged at a part of the outer circumferential surface 2a of the winding core part 2 along a film tip part 3a positioned at the beginning of winding of the film 3; and the method of manufacturing the same. In side view of the winding core part 2, an angle α between both ends of the elastic member 4 along a circumferential direction of the winding core part 2 and a center axis of the winding core part 2 is acute.
