A PAS resin composition which has fluidity optimal for insert molding and which can impart superior high- and low-temperature impact resistance to a molded body, and an insert-molded body formed using said resin composition are provided. This PAS resin composition includes a polyarylene sulfide resin having a terminal carboxyl group, an olefin copolymer, glass fibers and calcium carbonate. The weight-average molecular weight of the polyarylene sulfide is 15000-40000; as copolymer components, the olefin copolymer includes α-olefins, glycidyl esters of α,β-unsaturated acids, and acrylate esters, and the content of the copolymer component derived from the glycidyl esters in the resin composition is 0.2-0.6 mass%. Further, the fiber diameter of the glass fibers is 9-13μm, the average particle diameter of the calcium carbonate is 10-50μm, and the total content of glass fibers and calcium carbonate is 45-55 mass% of the resin composition. |
