To provide a laminated tube having excellent interlayer adhesion and durability thereof, while maintaining various properties, such as low-temperature impact resistance, burst pressure strength, and flexibility. [Solution] This laminated tube has at least two layers that are adjacent to each other, wherein an aliphatic polyamide composition that constitutes one layer includes: an aliphatic polyamide in which the ratio of the number of methylene groups to the number of amide groups is a specified value or more; and an elastomeric polymer which may contain a copolymerized polyamide having a specific unit, and a constitutional unit derived from an unsaturated compound having a carboxyl group and/or an acid anhydride group. |
