PROBLEM TO BE SOLVED: To provide a flexible pipe material which is excellent in flexibility and elasticity, is excellent also in dimension stability, has a light weight, has easy handleability, can be molded in a long size, can retain strength characteristics even into a long term outdoor use, further, does not generate toxic gas upon burning and is suitable for an inner pipe of sound absorbing pipe material and the like, to provide a method for manufacturing the flexible pipe material and, in addition, to provide a sound absorbing material which is made of the flexible pipe material and is excellent in sound absorbing characteristics.SOLUTION: A flexible pipe material comprises a resin hard ore material 4 and a belt-like body 1. The resin hard core material and the belt-like body are integrally melted. Therein, any of the following (1) to (3) is satisfied: (1) either of the resin hard core material 4 and the belt-like body 1 is spirally wound; (2) the resin hard core material is made of olefin type resin and/or polyester type resin; and (3) the belt-like body is non-woven fabric having the core part made of polyester resin and the sheath part is made of core sheath type fiber of a lower melting point resin than the polyester resin. |
