A polyarylene sulfide having a low amount of volatile components and a low chlorine content while having high melt fluidity is efficiently obtained. In an organic polar solvent, within a temperature range of 200 ° C. or more and less than 280 ° C., 95 to 105 mol of a dihalogenated aromatic compound and 0.01 to 5 mol of a monohalogenated compound with respect to 100 mol of the sulfidizing agent. In the method for producing polyarylene sulfide to be reacted, <Step 1> The polymerization time (T1a) in the temperature range of 230 ° C. to 245 ° C. is 30 minutes to 3.5 hours, and the dihalogenated aromatic at the end of the step The reaction is carried out so that the conversion rate of the compound is 70 to 98 mol%, and <Process 2> within the temperature range of 245 ° C. to 280 ° C., the polymerization time (T2) including the temperature rise / fall time is 5 minutes to 1 hour.
