PROBLEM TO BE SOLVED: To provide a pressure loss reduction type flexible pipe not impairing pressure loss of fluid flowing in the pipe. SOLUTION: This flexible pipe having a metallic bellows portion, is provided with an anisotropic extensible tube 3 free from its compressive deformation by being kept in a tensed state to the shaft center direction S of the bellows 2a, ..., and having smaller expanding and contracting property in the radial direction K in comparison with the shaft center direction S.
