Abstract
The present invention provides a liquid storage bag that offers high light-shielding properties with a simple structure, and a method for manufacturing the liquid storage bag. [Solution] The liquid storage bag comprises a bag body 22 and a supply unit capable of supplying the liquid sealed inside the bag body 22. The bag body 22 is formed by joining films 31 together. The film 31 forming the bag body 22 is a light-shielding film. The liquid is a photosensitive liquid. The bag body 22 has a joined end 26 formed by joining the films 31A and 31B to be joined at their peripheral edges. The joined end 26 has an uneven shape.
