PROBLEM TO BE SOLVED: To provide a polyamide composition with less thermal discoloration even exposed for many hours under high temperature while maintaining characteristics of polyamide. SOLUTION: This polyamide composition comprises, as the antioxidant, 0.01 to 3 pts.wt. of a hindered phenolic antioxidant (D), 0.01 to 3 pts.wt. of a pentavalent phosphorus antioxidant (E), and 0.01 to 3 pts.wt. of a trivalent phosphorus antioxidant each to 100 pts.wt. of a composition comprising 40 to 100 wt.% of a polyamide resin (A), 0 to 60 wt.% of a polyolefin resin (B), and 0 to 60 wt.% of an inorganic filler (C).
