PROBLEM TO BE SOLVED: To provide a transfusion bag which is easily handled by a nurse and the like, and reliably prevents opening of an easily peelable part from being forgotten.SOLUTION: The transfusion bag 10 has an IC chip and an antenna 43 connected to the IC chip, and includes an IC tag 40 disposed on one surface side of the easily peelable part 31 and a metal material 50 disposed on the other surface side of the easily peelable part 31. When the easily peelable part 31 is not opened, the antenna 43 and the metal material 50 are made close to each other and the IC tag 40 whose communication is interrupted can manage the open situation of the easily peelable part 31 by the fact that the antenna 43 is separated from the metal material 50 at a prescribed interval accompanying the opening of the easily peelable part 31 and communication is started. |
