SOLUTION: A puncture member 2 is constituted as follows. A puncture needle 3 covered with a needle cover 4 having elasticity is provided to one end of a body 7 in a protruded state and a puncture needle 5 covered with a needle cover 6 having elasticity is provided to the other end thereof in a protruded state. When the needle covers 4 and 6 are inserted into fitting parts 13 and 24 of a mouth plug part 12 of a medicinal liquid container 11 or an infusion container 21 together with the puncture needles 3 and 5, they become a contracted state in the fitting parts 13 and 24. When the covers are pulled out from the fitting part 13 and 24 of the mouth plug parts 12 and 23 together with the puncture needles 3 and 5, they are again returned to the original shapes to again cover the puncture needles 3 and 5.
