PROBLEM TO BE SOLVED: To provide a liquid storage container which is easy to attach to an apparatus, excellent in the discharging efficiency of the content even when the highly viscous content is sucked to discharge, less costly in transport and storage, and easy in disposal. SOLUTION: This flexible liquid storage container which is substantially rectangular parallelopiped box in contour when filled with the content, provided with a mouth member 5 mounted on a front surface 1 to enable the filling or the discharge of the content comprises a thick-walled film A forming four continuous surfaces, i.e., the front surface 1, an upper surface 2, a back surface 2 and a lower surface 3 and a thin-walled film forming two surfaces, i.e., right and left side surfaces 6 and 7. The film B comprising the two surfaces is folded so that surfaces to be bonded are outside, and is formed by bonding the film A comprising the four surfaces to the periphery thereof while inserted into an inner surface of the thick-walled film A of the four surfaces, and the folding is made on a ridge of each boundary of the surfaces of the film A.
