PROBLEM TO BE SOLVED: To provide a material for precision molding of an optical part comprising a polyphenylene sulfide resin composition, having excellent molding processability in injection molding or the like and heat dissipation, free from or hardly causing burr at molding, and also having excellent mechanical strength and heat resistance. SOLUTION: The polyphenylene sulfide resin composition for the precision molding of the optical part, having excellent heat dissipation, molding processability, mechanical strength and heat resistance, and free from or hardly causing burr at molding is obtained by compounding (b) 10-80 pts. wt. polyphenylene ether resin having 5,000-50,000 poise melt viscosity at 300°C at 500 sec<SP>-1</SP>shear rate, (c) 40-200 pts. wt. carbon fiber having≥100 W/mK heat conductivity and (d) 0-150 pts. wt. graphite having 1-200μm average particle diameter, with (a) 100 pts. wt. polyphenylene sulfide resin having 300-3,000 poise melt viscosity at 300°C at 500 sec<SP>-1</SP>sear rate.
