<p>PROBLEM TO BE SOLVED: To provide a heat insulated hose capable of surely avoiding generating of dew condensation while suppressing reduction of flexibility. SOLUTION: A belt shaped plastic foaming body 8 and the like are spirally wound so as to form an inside heat insulating layer 9, a belt shaped plastic foaming body 10 and the like are spirally wound around the outside of the inside heat insulating layer 9 so as to form an outside heat insulating layer 11, and a covered material 12 for covering from the outer surface of the outside heat insulating layer 11, to the range extending at least an outer surface 8B of the plastic foaming body 8 which is spirally wound in order for forming the inside heat insulating layer 20 from between joining surfaces 10A, 10A of both plastic foaming bodies 10, 10 which are spirally wound in order for forming the outside heat insulating layer 11, is made of olefin resin capable of thermally fusing with the outside heat insulating layer 11 and the inside heat insulating layer 9.</p> |
