Abstract A liquid collecting tube for receiving blood or liquid for inspection is disclosed, which has a tubular member (1) and a closure member (2) for closing an open end (1a) of the tubular member (1) and made of a material capable of being pierced by a piercing needle (5). The closing member includes a sealing member (3) for holding the open end of the tubular member sealed when taking out the liquid (9) form the tubular member with a take-out tool (8) and a separable member (4) separablly laminated on the outer side of the sealing member. The separable member is removed so that only the sealing member remains on the tubular member when taking out liquid. The sealing member is film-like and can be readily broken by the take-out tool such as a pipette.
