Provided is a thermoplastic elastomer composition comprising a polyamide resin and a modified rubber, in which low temperature resistance is improved. The thermoplastic elastomer composition comprising the polyamide resin and the modified rubber having an acid anhydride group or an epoxy group is characterized in that the modified rubber having an acid anhydride group or an epoxy group is modified with a secondary amine. The secondary amine is preferably a compound having a structural formula: R1—NH—R2, in which R1 is a linear alkyl group having 1 to 30 carbon atoms and R2 is a hydrocarbon group having 1 to 30 carbon atoms or a hydrocarbon group having 1 to 30 carbon atoms and having a hydroxyl group, a sulfonyl group, a carbonyl group or an ether bond.
