The present invention provides a tank having a mechanical part, a molding processability and an airtightness, and a method for producing the same, comprising a container formed by molding polyarylene sulfide and a die obtained by chemically treating a metal surface. A polyarylene sulfide having a melt viscosity of 500 to 30000 poise measured using a die having a diameter of 1 mm and a length of 2 mm under the conditions of a temperature of 315 ° C. and a load of 10 kg using a Koka flow tester. A tank comprising 99.9% by weight, carnauba wax 0.1 to 3% by weight, and in some cases, a container part comprising a fibrous filler and / or an inorganic filler, and a die having a chemically treated metal surface.
