Provided is a method for producing polyarylene sulfide efficiently in a short time with a high polymerization reaction rate. A process for producing a polyarylene sulfide, characterized in that at least a sulfidizing agent and a polyhalogenated aromatic compound are subjected to a polymerization reaction in the presence of an organic phosphorus salt having the structural formula of the following general formula (I): . (However, R1, R2, R3 and R4 are substituents containing hydrogen, an alkyl group, an aromatic group, phosphorus, nitrogen, sulfur and the like, and Q − is an anion.) [Selection figure] None |
