ABSTRACT:
A heat insulated hose includes a cylindrical member. This cylindrical member is formed by helically winding a laminated tape having a base layer of a foamed resin, a permeable coat film laminated on an inner surface of the base layer, and an air-tight coat film laminated on an outer surface of the base layer, with adjacent side edges thereof abutted against each other. A resin reinforcing member is helically wound on an outer peripheral surface or inner peripheral surface of the cylindrical member in a manner striding over the adjacent side edges of the laminated tape. The respective side edges of the laminated tape is thermally fused with the resin reinforcing member, thereby integrally joining between the adjacent side edges.
