PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer composition excellent in workability and dynamic fatigue durability.SOLUTION: A thermoplastic elastomer composition includes (A) a thermoplastic resin, (B) a halogenated isoolefin/para-alkylstyrene copolymer rubber, and (C) a thermoplastic elastomer, in which the thermoplastic resin (A) forms a continuous phase; the halogenated isoolefin/para-alkylstyrene copolymer rubber (B) and the thermoplastic elastomer (C) are separately dispersed in the continuous phase; the halogenated isoolefin/para-alkylstyrene copolymer (B) is crosslinked; the thermoplastic elastomer (C) is not crosslinked, and the amount of the thermoplastic elastomer (C) is 20-50 mass% with respect to the total amount of the halogenated isoolefin/para-alkylstyrene copolymer rubber (B) and the thermoplastic elastomer (C). |
