To provide a polyamide resin composition excellent in weatherability.

The polyamide resin composition comprises (A) 100 pts.wt. of a polyamide resin, (B) 0.1-30 pts.wt. of carbon black, and (C) 0-200 pts.wt. of an inorganic filler. In the carbon black, an average primary particle size is 10-25 nm, and a DBP oil absorption is 70 ml/100g or more. Preferably, the carbon black (B) has the average primary particle size of 14-20 nm, and the DBP oil absorption of 70-150 ml/100g.
