PROBLEM TO BE SOLVED: To provide a multilayered pipe excellent in gas barrier properties, stretching deformation resistance, heat shrinkage followability and molding processability. SOLUTION: The multilayered pipe contains at least one layer of an ethylene/vinyl alcohol copolymer (A) containing a structural unit having a 1,2-glycol bond in its side chain represented by formula (1) (wherein X is an arbitrary bonding chain excepting an ether bond, R1-R4 are each independently an arbitrary substituent and n is 0 or 1).
