A method is provided for obtaining a polyarylene sulfide resin composition with a low chlorine content, which has high fluidity and high quality and produces less burrs. Specifically, a method is provided wherein a polyarylene sulfide resin composition is produced by melting and mixing (A) a polyarylene sulfide resin, (B) an inorganic filler, and (C) an alkoxysilane compound. In this method, (A) a polyarylene sulfide resin having a melt viscosity of 80-400 Pa&#xb7;s (at a temperature of 310&#xb0; C. and a shear rate of 1200/sec) and a chlorine content of 1000-2000 ppm is supplied from a raw material feed port of a specific extruder, and then extruded at two kneading parts within the range of [shear rate (1/sec)&#xd7;kneading time (sec)=1600-6000], thereby producing a polyarylene sulfide resin composition having a melt viscosity of 150-330 Pa&#xb7;s (at a temperature of 310&#xb0; C. and a shear rate of 1200/sec) and a chlorine content of not more than 950 ppm.
