description Provided are a polyarylene sulfide resin composition having excellent mechanical strength and excellent moisture and heat resistance, a molded article thereof, an inorganic filler used for the composition, and methods for producing them. More specifically, provided are a polyarylene sulfide resin composition including 100 parts by mass of a polyarylene sulfide resin and 1 to 100 parts by mass of an inorganic filler surface-treated with a sizing agent, wherein the sizing agent is a sizing agent (α) containing at least a urethane-modified epoxy resin having an alkoxy polyoxyalkylene structure and a urethane resin having a sulfonate group, a sizing agent (β) containing a copolymer (β1) having a mass average molecular weight of 5000 to 150000, which is obtained by radical copolymerization of a polymerizable monomer mixture of at least a (meth) acrylic acid ester and maleic acid (anhydride), or a sizing agent (γ) containing at least a polyether resin, a urethane resin, and a silane coupling agent, a molded article thereof, an inorganic filler used for the composition, and methods for producing them.
