ABSTRACT The blood collecting tube of the present invention has a tubular body that is opened at one end and closed at the other end and a sealing member which is bonded to the peripheral edge of the opening of the tubular body so as to seal this opening. Also, the blood collecting tube of the present invention has a tubular body that is opened at one end and is closed at the other end and a sealing member which can be pierced by a hollow needle and is bonded to peripheral edge of the opening of the tubular body to seal the opening in which the internal pressure of the tubular body is suitably reduced in accordance with the amount of blood to be collected, and the aforesaid sealing member is made up of: a gas barrier member having high air-tightness for substantially maintaining the degree of reduction in the internal pressure of the blood collecting tube during a period up to blood collection; and a sealing element capable of stopping up the needle hole which might remain after extraction of the hollow needle which has been stuck into the sealing member for blood collection. Accordingly, it is possible to provide a blood collecting tube which does not require any unplugging operation for extracting the plug from the opening of the tubular body when blood is to be collected by means of a needle for testing purposes, thereby realizing easy handling. Also, since the airtightness of the tubular body is maintained during a period from production to use, a hollow needle can be easily stuck through the sealing member, and it is possible to positively assure the liquid-tightness after the hollow needle has been extracted from the sealing member.
