In order to improve fatigue durability of a thermoplastic elastomer composition composed of a matrix phase of a thermoplastic resin and dispersed phases of a rubber, the thermoplastic elastomer composition comprises (A) 100 parts by weight of a halogenated poly (isoolefin-co-p-alkylstyrene ) rubber, (B) 40 to 120 parts by weight of a polyamide resin, and (C) 0.5 to 10 parts by weight of an amine having at least one hydroxyl group. The amine (C) having at least one hydroxyl group is preferably a compound represented by formula (1) : where R1 is a C1-30 alkyl; R2 is -(C2H4O)n-H, where n is an integer of 1 to 30; and R3 is -(C2H4O)m-H, where m is an integer of 1 to 30, a C1-30 alkyl, or hydrogen. |
