SYRINGE, DRUG SOLUTION INJECTOR, SEALING MEMBER AND METHOD FOR PRODUCING SEALING MEMBER

摘要

The purpose of the present invention is to provide a syringe which is provided with a sealing member that exhibits good sliding performance, while being suppressed in separation of an ultra high molecular weight polyethylene film. A syringe (1) is provided with a cylinder (2) and a sealing member (4) that is in contact with the inner surface of the cylinder (2) and is slidable within the cylinder (2). This syringe (1) is characterized in that: the sealing member (4) comprises a base (40) and an ultra high molecular weight polyethylene film (6) that is bonded onto the base (40); the ultra high molecular weight polyethylene film (6) has an ultra high molecular weight polyethylene layer (61) and an adhesive film layer (62); and the ultra high molecular weight polyethylene film (6) is bonded to the base (40) by means of the adhesive film layer (62).
