Beschreibung
Zusammenfassung:	To provide a hose having excellent durability, such as heat resistance and oxidation resistance, a polyamide resin composition includes: a polyamide(A), a polyolefin elastomer (B), a phenolic antioxidant (C), a sulfur-based antioxidant (D), and a metal deactivator having a hindered phenol structure (E). The phenolic antioxidant (C) is a different substance from the hindered phenolic metal deactivator (E). Based on 100 parts by weight of the polyamide (A) and the polyolefin elastomer (B) in total, the content of the phenolic antioxidant (C) is 0.2 parts by weight or more, the sulfur antioxidant (D) is 0.2 parts by weight or more, and the metal deactivator (E) is 0.01 parts by weight to 1.5 parts by weight. A barrier layer 2 of a hose 1 produced using a polyamide resin composition having such a composition not only has high durability, such as heat resistance and oxidation resistance, but also has high gas barrier properties.
