Poly(arylene sulfide) resin composition and insert-molded article

Abstract

[Problem] To provide: a polyarylene sulfide resin composition having excellent high- and low-temperature impact properties and excellent low warpage; and an insert-molded article using the resin composition. [Solution] A polyarylene sulfide resin composition that contains a polyarylene sulfide resin A, an inorganic filler B, and an olefinic copolymer C containing a structural unit derived from an α-olefin and a structural unit derived from a glycidyl ester of an a, p-unsaturated acid, the inorganic filler B containing a fibrous inorganic filler B1 having a different diameter ratio, which is a ratio of the major axis to the minor axis of a cross section perpendicular to the longitudinal direction, of 1.5 or less, and a fibrous inorganic filler B2 having a different diameter ratio of 3.0 or more, the mass ratio B1/B2 of the fibrous inorganic filler B1 and the fibrous inorganic filler B2 being 0.2 or more and 5.0 or less.
