The present invention aims to provide a glass-fiber-reinforced polyamide resin composition, characterized in that, the composition contains a crystalline aliphatic polyamide resin (A), an amorphous polyamide resin (B), an acrylic resin (C), mica (D), glass fiber (E) and a master batch of carbon black (F) in a ratio by mass of (17 to 30):(10 to 16):(3 to 8):(10 to 25):(20 to 50):(1 to 8), respectively, in that, a mass ratio of (A) and (B) ((B)/(A)) satisfies 0.50 to 0.61, and in that, the composition further contains a copper compound (G) in a rate of 0.005 to 1.0 part by mass when a total amount of the ingredients (A) to (F) is taken as 100 parts by mass. From the glass-fiber-reinforced polyamide resin composition, it is possible to obtain a molded product that is highly excellent in a surface appearance (textured surface uniformity) and has a weather resistance in a level being enough for maintaining an excellent surface appearance even after the weathering test.
