PROBLEM TO BE SOLVED: To provide a polyarylene sulfide resin composition having remarkably excellent environmental stability of laser foci and mechanical strength, melt fluidity and even reduced flash properties in good balance. SOLUTION: This polyarylene sulfide resin composition comprises (a) 100 pts.wt. of a polyarylene sulfide resin having <=80 Pa.s melt viscosity (at 310 deg.C and 1,000/s shear rate), (b) 5-80 pts.wt. of graphite, (c) 25-180 pts.wt. of a nonfibrous filler other than the graphite and (d) 25-180 pts.wt. of a fibrous filler. An optical pickup part is obtained by injection molding the polyarylene sulfide resin composition. |
