A liquid storage container includes a liquid containing body that is formed of a flexible film and contains liquid therein; a liquid lead-out member connected to the liquid containing body; and a spacer member disposed in the liquid containing body. The liquid containing body deforms in a direction in which inner wall surfaces of the flexible film facing each other are brought into contact with each other at the time of reduction in the remaining amount of the liquid as the inside liquid is taken out through the liquid lead-out member, and the spacer member regulates contact between parts of the inner wall surfaces of the flexible film facing each other at the time of reduction in the remaining amount of the liquid to thereby form a remaining liquid space where liquid remains.
