Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a polyarylene sulfide having a high molecular weight and excellent heat stability. SOLUTION: This method for continuous production of polyarylene sulfide is characterized in that in a method in which the polyarylene sulfide is continuously produced from a sulfur source and a dihalogenated aromatic compound in an aprotic organic solvent, the content of the dihalogenated aromatic compound in the polymerization solution after substantial completion of the polymerization reaction is >=5 mg/g.
