PROBLEM TO BE SOLVED: To provide a film cutting device which can efficiently manufacture a large-size circular release film.SOLUTION: A film cutting device includes a rotation member 3, a rotation arm 7, and a cutter 9. The rotation member 3 and the cutter 9 are respectively connected directly or indirectly to one end of the rotation arm 7 and the other end of the rotation arm 7. The cutter 9 stabs a predetermined position of the film by moving the cutter 9 to a film surface, and passes inside the rotation member 3, and the rotation member 3 rotates around a rotation axis approximately vertical to a film surface. Thereby, the cutter 9 stabbed on the film and the rotation arm 7 rotates to cut the film in a circular shape.
