A laminated tube excellent in breaking pressure, chemical resistance, interlayer adhesion, and durability at high temperatures while maintaining various properties such as chemical solution barrier properties, low temperature impact resistance, and elution resistance of monomers and oligomers. I will provide a. A laminated tube of three or more layers including (a) layer, (b) layer, and (c) layer, wherein the (a) layer includes a specific aliphatic polyamide composition (A). The (b) layer includes a polyamide composition (B) including a specific polyamide (B1) and an elastomer polymer (B2), and the (c) layer includes a specific semi-aromatic polyamide (C1) or a semi-polymer. A laminated tube containing a semi-aromatic polyamide composition (C) containing an aromatic polyamide (C2). [Selection figure] None |
