PROBLEM TO BE SOLVED: To suppress generation of fusion flash of ejection member through a simple structure, and to satisfactorily maintain a melt-sticking state between a resin sheet and the ejection member.SOLUTION: A reservoir bag 10 includes: a reservoir body 40 for storing a reserve; and a drain terminal 50 which is melt-stuck to a seal part 44. The drain terminal 50 is equipped with a nearly boat-shaped installation part 54 which is long along the extending direction of the seal part 44 to be melt-stuck and which has a prescribed thickness in the direction orthogonal to the extending direction. In the outer part 70a of the installation part 54, there are installed a melt-sticking part 82 to which a resin sheet 42 is melt-stuck and a non-melt-sticking part 84 to which no resin sheet 42 is melt-stuck in the corner 80a on a storage chamber 41 side among the ends 80 projecting at least along the extending direction.SELECTED DRAWING: Figure 2 |
