Zusammenfassung:	Provided is a seal member, comprising a main body part, a closed end part, and a cleavable part. The main body part further comprises an aperture part which is formed in the proximal end thereof, and a tight contact part which is capable of forming a fluid-tight seal with an inner wall of a cylinder body. The closed end part is formed integrally and continuously with the main body part at the distal end of the main body part, and seals off the distal end of the main body part. The cleavable part is formed in the closed end part, and is connected with the aperture part. The cleavable part cleaves by a prescribed pressure being applied in a drug solution storage space, and a liquid transmission aperture which connects with the aperture part is formed in the closed end part.
