To obtain a reinforced polyamide resin composition excellent in discoloration resistance and mechanical properties even in environments of a high- temperature atmosphere and ultraviolet exposure.

This polyamide resin composition is obtained by further including an inorganic pigment in an amount of 1-30 pts.wt. based on 100 pts.wt. of a polyamide resin and a phosphorus compound in an amount of 0.0005-0.2 pt.wt. based on 100 pts.wt. of the polyamide resin and expressed in terms of phosphorus element in the polyamide resin composition prepared by including an inorganic filler in an amount of 10-200 pts.wt. based on 100 pts.wt. of the polyamide resin therein.
