A liquid storage container which can be securely inflated within an external container. The liquid storage container includes a bag body and an ejection outlet. The bag body includes a plurality of bellows portions formed by accordion-folding the bag body along longitudinal crease lines, and has a double-folded portion formed by folding the bag body along an upper lateral crease line and a lower lateral crease line. With reference to the bag body, the following relations are satisfied: 10%&#x3c;X/H&#x3c;50%, 3%&#x3c;Y/H&#x3c;10%, where H is the length of the bag body, x is the distance between the top periphery and the lower lateral crease line, and Y is the distance between the upper lateral crease line and the lower lateral crease line.
