Patent ID: 8669310

Claim:
A polyamide resin composition reinforced with glass fiber produced by the melt kneading of a mixture where 66 to 80 parts by weight of glass fiber bundles (B) comprising a glass fiber having a flat cross section whose flatness degree is 1.5 to 8 and having an ignition loss at 625° C. for 0.5 hour of not more than 0.8% by weight are added to 34 to 20 parts by weight of polyamide (A), characterized in that, during the above melt kneading, a polyamide-reactive silane coupling agent (C) is added to the above mixture in a rate of 0.1 to 1.0% by weight of the above glass fiber bundles (B), wherein the polyamide resin (A) is constituted from an aliphatic polyamide (a1) and a polyamide (a2) containing aromatic components, and their constituting ratio by weight is (5 to 95):(95 to 5), and wherein the polyamide resin composition does not contain a flame retardant.
