Abstract

To provide a new liquid storage tube with supplied liquid having a following body that can bring about good temporal stability, clear drain performance and gas barrier performance.SOLUTION: A liquid storage tube 100 with supplied liquid comprises a liquid supply part 10 and a liquid storage part 20. In the liquid storage part 20 are stored supplied liquid 30 and a multi-layered following body 40 in this order, from the liquid supply part 10 side. The multi-layered following body 40 includes at least a first following body 42 and a second following body 44. The first following body 42 is arranged closer to the liquid supply part 10 than the second following body 44, and the first following body 42 contains first base oil. The second following body 44 contains second base oil, and a ratio of a specific gravity of the first following body 42 to a specific gravity of the second following body 44 is over 1.05.SELECTED DRAWING: Figure 1
