Beschreibung
Zusammenfassung:	A polyarylene sulfide-derived resin composition which has flowability optimal for insert molding and which can impart superior high- and low-temperature impact properties to a molded body, and an insert-molded body using the resin composition. The resin composition includes a polyarylene sulfide resin having carboxylic terminal groups, an olefin-derived copolymer, glass fibers and calcium carbonate. The weight-average molecular weight of the polyarylene sulfide resin is 15,000-40,000; as copolymerization components, the olefin-derived copolymer includes α-olefins, glycidyl esters of α,β-unsaturated acids, and acrylic esters, and the content of the copolymerization 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 9-13 μm, the average particle diameter of the calcium carbonate is 10-50 μm, and the total content of glass fibers and the calcium carbonate is 45-55 mass % of the resin composition.
