A polyamide resin composition with high stiffness, excellent in surface smoothness, surface glossiness and weather-color fastness without coating. This polyamide resin composition is characterized by that
0.2 to 5 parts by mass of a carbon black; and
0.01 to 10 parts by mass of a weathering agent;
are incorporated on the basis of 100 parts by mass in total of
30 to 90 parts by mass of a mixed polyamide resin containing a crystalline polyamide resin of 50 to 95 % by mass and a non-crystalline polyamide resin of 50 to 5 % by mass in such a way as to give 100 % by mass in total, and
10 to 70 parts by mass of a reinforcement material.
