<P>PROBLEM TO BE SOLVED: To provide a plasticizer for a polyarylene sulfide (PAS) resin capable of imparting toughness without reducing a modulus of elasticity at a broad environmental temperature, and to provide a molded product of the polyarylene sulfide (PAS) resin excellent in a balance between toughness and stiffness with the use of the plasticizer. Ž<P>SOLUTION: This plasticizer for the polyarylene sulfide resin comprises a metal fine particle which contains at least one metal species selected from among copper, nickel, zinc, cobalt, iron and manganese. The molded product of the polyarylene sulfide resin which contains the plasticizer has a stretching elongation change of ≥120% at -20 to 120°C and an elastic modulus change of ≥90% at -20 to 120°C. The method for enhancing a degree of elongation of the polyarylene sulfide resin is also disclosed in which the metal fine particle which contains the metal species is dispersed in the polyarylene sulfide resin phase.
