Summary:PROBLEM TO BE SOLVED: To provide a flexible pipe for fluid transportation, having low temperature resistance and excellent flex resistance.SOLUTION: A flexible pipe 1 includes an interlock pipe 3 which is mostly tubular, a resin layer 5, an internal pressure resistance reinforcing layer 7, a band-shaped body pressing layer 9, an axial force reinforcing layer 11, a protective layer 13, etc. In the outer periphery portion of the interlock pipe 3, the resin layer 5 is formed. The resin layer 5 blocks a fluid flowing through the interlock pipe 3. The resin layer 5 includes a polyolefin-based composition, in which more than one copolymers selected from a group composed of (A)ethylene propylene copolymer 60-90 pts.mass, (B) polyolefin and ethylene copolymer (excluding ethylene propylene copolymer) are contained at 10-40 pts.mass.
