PROBLEM TO BE SOLVED: To obtain the subject resin composition excellent in moldability and processability, free from or extremely slight in occurrence of burr in molding, improved in rigidity and dimensional accuracy, by blending a polyphenylene sulfide resin with a specific resin and a prescribed inorganic filler. SOLUTION: This composition comprises (A) a resin composition obtained by blending 60-95wt.% of a polyphenylene sulfide resin having 300-3,000 poise melt viscosity at 300 deg.C at 500 second<-1> shear rate with 40-5wt.% of a polyphenylene ether resin having 5,000 to 50,000 poise melt viscosity, (B) an inorganic filler composed of kaolin and talc and (C) a fibrous inorganic filler, an inorganic filler except the filler or its mixture. Preferably 100 pts.wt. of the component A is mixed with 60-180 pts.wt. of the component B and 50-250 pts.wt. of the component C in the ratio of <=400 pts.wt. of the total of the components B and C. Preferably the component B is obtained by blending 70-30wt.% of kaolin having 0.1μm-0.4μm average particle diameter with 20-80wt.% of talc having 0.5-2.7μm average particle diameter.
