PROBLEM TO BE SOLVED: To provide a glass fiber-reinforced flame-retardant polyamide resin composition having extremely high flame retardancy, hardly generating a hydrogen halide gas exhibiting high corrosivity at the time of burning, and having both of excellent electric characteristics and excellent mechanical characteristics. SOLUTION: This glass fiber-reinforced flame-retardant polyamide resin composition comprising (a) 30-70 wt.% polyamide resin, (b) 10-40 wt.% melamine phosphate-based flame retardant and (c) 5-50 wt.% glass fiber is characterized in that the glass fiber (c) is surface-treated with (d) a sizing agent containing a copolymer of maleic anhydride and an unsaturated monomer and/or an acrylic copolymer, and a silane-based coupling agent.
