A film cassette includes a film roll, a cassette case and a roller portion. The film roll is a wound film for packaging. The cassette case is configured to rotatably house the film roll, and includes a discharge opening from which the film pulled out from the film roll is discharged to the outside of the cassette case. The discharge opening extends in a direction parallel to a first rotation axis, which is a rotation axis of the film roll. The roller portion is rotatably supported by the cassette case in the vicinity of the discharge opening. The roller portion is rotatable around a second axis, which extends parallel to the first rotation axis.
