PROBLEM TO BE SOLVED: To provide a hose which has an innermost layer hardly deteriorated even if repeatedly exposed to a high temperature, and has resistance to hydrogen gas permeability and water vapor and anti-contamination properties to transported gas. SOLUTION: This hose has at least an internal pipe, which has an innermost layer formed of a fluorine-containing ethylenic polymer with a functional group (A), and a metallic laminate layer formed of an organic material layer 1 composed of an organic material composition which contains at least an organic material with a functional group (B) indicating affinity or reactivity to the functional group (A) and metallic foil. In this case, the metallic laminate layer is arranged outside the innermost layer so as to allow the organic material layer 1 to face the innermost layer side. COPYRIGHT: (C)2007,JPO&INPIT
