<P>PROBLEM TO BE SOLVED: To provide a polyarylene sulfide resin composition which is dramatically excellent in the environmental stability of a laser focusing and is well- balancedly excellent in the mechanical strengths, melt flowability and little burring, and to provide a light pick-up parts using it. <P>SOLUTION: The resin composition comprises 100 pts.wt. of (a) a polyarylene sulfide resin, 1-15 pts.wt. of (b) carbon black which has such a surface carbon atom concentration of 98.0% or more as determined by the X-ray electron spectroscopy, 40-180 pts.wt. of (c) a nonfibrous filler with the exception of (b), and 25-180 pts.wt. of (d) a fibrous filler. <P>COPYRIGHT: (C)2003,JPO |
