To provide a laminated structure having high heat resistance and low fuel permeability while having good flexibility. SOLUTION: The polyamide-based thermoplastic elastomer composition includes an outer layer (A) made of a polyamide-based thermoplastic elastomer composition and an inner layer (B) containing a thermoplastic resin, and the polyamide-based thermoplastic elastomer composition has a melting point of 200 to 290 ° C. -Based polyamide [I], ethylene / α-olefin / nonconjugated polyene copolymer rubber [II], olefin-based polymer [III] containing a predetermined amount of functional group structural unit, and phenol resin-based crosslinking agent [IV] And a thermoplastic resin is at least one member selected from the group consisting of semi-aromatic polyamides and the like.
