Zusammenfassung:	Provided is a film which is prevented, when extended transversely of its transfer direction, from being longitudinally extended, so that it is extended selectively in one axis direction. A film (F) is transversely extended while being gripped by using a clip (2) having a corrugated upper tooth portion (a holding member piece) (12) and a corrugated lower tooth portion (a holding member piece) (11). After shaped to have corrugations by corrugated grip members (6a and 6b), the film (F) is transversely extended while being held by the clip (2) having those holding members.
