A polyarylene sulfide resin composition obtained by melt-mixing a mixture comprising resin components comprising as main resins (A) a polyarylene sulfide resin and (B) a polyorganosiloxane graft copolymer obtained by graft-polymerizing one or more kinds of vinyl monomer containing at least an epoxy group-containing vinyl monomer onto a compound rubber in which a polyorgano- siloxane rubber and a polyalkyl (meth)acrylate rubber have been inseparably united with each other. The composition of the present invention, whether it contains a filler or not, is excellent in compatibility between the polyarylene sulfide resin and polyorgano- siloxane graft copolymer. If this composition is extrusion-molded or injection-molded under the common molding conditions, it keeps its original dispersed and mixed condition without showing a phase separation. Consequently, this composition has an excellent perform- ance that impact resistance also has been given to the polyarylene sulfide resin without largely injuring excellent properties inherent to the resin.
