Abstract:
1. A resin composition comprising from 30 to 90% by mass of a polyamide (A), from 70 to 10% by mass of glass fibers (B), a copper compound (C), and a halogenated compound (D), wherein: the polyamide (A) has a sum of a terminal carboxyl group concentration and a terminal amino group concentration of 100 milliequivalents/kg or more and 200 milliequivalents/kg or less and the terminal carboxyl group concentration is higher than the terminal amino group concentration; the glass fibers (B) have a fiber diameter from 10 to 20 μm, a weight average fiber length from 5 to 30 mm, and a twisted form; a content of copper based on polyamide (A) is 30 ppm or more and 200 ppm or less; a molar ratio of halogen to copper (halogen/copper) is more than 5 and not more than 25; the resin composition is in the form of pellets, and the glass fibers (B) have a weight average fiber length greater than the length of the pellets; and the halogenated compound (D) is present as particles having a particle size of 20 μm or less in the resin composition.
