Zusammenfassung:PROBLEM TO BE SOLVED: To provide a liquid storage container with improved barrier and/or sealing performance which is durable after repeated use.SOLUTION: The liquid storage container having a container body 2 and lids 3 and 4. A body-side fluorinated layer 2b is formed on the inner surface of the container body. An inner-lid-side fluorinated layer 3b is formed on the inner surface of the lid. The ratio A/B between a surface analysis value A per 1,200 cmmeasured by a Fourier transform infrared spectrophotometer (FT-IR) in the lid-side fluorinated layer and a surface analysis value B per 1,200 cmmeasured by a Fourier transform infrared spectrophotometer (FT-IR) in the body-side fluorinated layer is more than 0.6 and less than 1.
