PROBLEM TO BE SOLVED: To provide a tank composed of a vessel part formed by molding polyallylene sulfide and a mouth piece made of a metallic surface chemically treated, and superior in a mechanical characteristic, molding workability and airtightness; and its manufacturing method. SOLUTION: This tank is composed of the vessel part composed of the polyallylene sulfide of 97 to 99.9 wt.% and camauba wax of 0.1 to 3 wt.% having melt viscosity of 500 to 30000 poise measured by using a die having a diameter of 1 mm and the length of 2 mm under a condition of the measuring temperature of 315°C and a load of 10 kg by an elevated type flow tester, also, a fibered filler and/or an inorganic filler in case, and the mouth piece made of the metallic surface chemically treated.
