PROBLEM TO BE SOLVED: To inexpensively provide a hose superior in handling easiness and workability, superior also in chlorine resistance and suited as, for instance, a service water pipe, a pipe for supplying water or hot water and an antifreeze liquid pipe for heating by providing sufficient softness and superior flexibility causing no kink even when excessive mechanical external force is applied. SOLUTION: The hose 1 comprises a tube molded in a tubular shape from a composite containing polyolefin system resin and an intermediate layer 3 formed on an outer periphery of the tube 2. In the hose 1, forming material of the intermediate layer 3 comprises a composite containing amorphous polyolefin. In the hose 1, the tube 2 is cross-linked by electron beam irradiation. In the hose 1, the polyolefin system resin is a mixture of polyethylene and ethylene-α-olefin copolymer. COPYRIGHT: (C)2005,JPO&NCIPI
