(57) [Problem] To provide a liner for a high-pressure gas container and a high-pressure gas container excellent in gas barrier properties, pressure resistance and impact resistance. SOLUTION: This is a liner 1 for a high-pressure gas container manufactured using a resin composition comprising a polyphenylene sulfide resin. The above resin composition has a gas permeability coefficient of methane gas at 40 ° C. of 1.7 × 10 −16 mol · m / m. 2 · s · Pa or less, and the tensile elongation at break at 23 ° C. is 50% or more. The resin composition preferably has an Izod impact strength at 23 ° C. of 500 J / m or more. |
