Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a gasket excellent in capping property, liquid tightness and slidability, in a gasket laminated with an inactive resin film used for a glass-made or resin-made syringe.SOLUTION: In a gasket laminated with an inactive resin film and having a plurality of annular ribs brought into slide contact with a syringe inner wall, the slide contact part cross section of a tip annular rib is widened in a substantially liner manner, the length of a straight part is 10-55% with respect to the length of a slide side surface part, and a diameter enlarging ratio X of a substantially linear diameter to a syringe rear end direction with respect to a minimum diameter r (mm) and a maximum diameter R (mm) of the straight part is 0.1-8.0%.
