Zusammenfassung:	PURPOSE: To produce a cassette with which velvet is not torn or unallowably deformed at the edge of a lower lip by adhering the strip for light shield of lower lip at an opening part for film to metal so that the surface from 10% to 60% of entire surface of the strip for light shield can not be adhered to a metal strip. CONSTITUTION: The edge area of the strip for light shield on the narrow side and the edge area of the strip for light shield on the lengthwise side are completely adhered to metal at a lower lip 3 and further, the edge area of the strip for light shield on the lengthwise side is completely or partially adhered to metal inside the cassette. Then, the entire part or one part of inside area on the surface of the strip for light shield is not adhered to metal but the strip for light shield of the lower lip 3 at the port part for film is adhered to metal so that the area from 10% to 60% of the entire surface of the strip for light shield can not be adhered to a metal strip 4. Thus, the cassette for film, with which the velvet is not torn or unallowably deformed during work for sharply curving the lower lip 3, can be produced.
