PURPOSE:To provide the titled molded article composed mainly of a polyarylene sulfide and containing a specific diphenyl ether compound, producible easily and stably by melt-molding process at a low cost and having high strength and excellent toughness and low-temperature characteristics. CONSTITUTION:The objective molded article can be produced by compounding (A) a polyarylene sulfide (preferably a polyphenylene sulfide composed mainly of poly-p-phenylene sulfide) or a blended composition of the polyarylene sulfide and other polymer with (B) a diphenyl ether compound of formula I (R1 is organic group; R2 is H or organic group such as alkyl, phenyl, arylene, etc.), preferably a compound of formula II, III, etc. (A1 and A2 are alkyl; n>=1; m>=1) before or during the melt-molding of the component A at a ratio to give a molded article containing >=0.01wt%, preferably 0.1-20wt% component B.
