Provided are a device for continuously producing poly(arylene sulfide) (hereinafter, referred to as PAS) and a method for continuous PAS production with which resource savings, energy savings, and a reduction in equipment cost are rendered possible. The device for continuous PAS production according to the present invention includes a housing chamber for housing a plurality of reaction cells; wherein the housing chamber is supplied with at least an organic amide solvent, a sulfur source, and a dihalo aromatic compound. In the reaction cells, the sulfur source is polymerized with the dihalo aromatic compound in the organic amide solvent to form a reaction mixture. The reaction cells communicate with each other through a gas phase within the housing chamber. The reaction cells are sequentially connected, and the reaction mixture sequentially moves to each reaction cell.
A method for continuously producing poly(arylene sulfide) by carrying out simultaneously the steps of:
