A laminated hose is present which is suitable for a fuel conducting hose or other hose, or diaphragm, used for example in an automotive vehicle, which structure is required to have excellent heat resistance and gasoline permeation resistance while maintaining suitable properties of bonding and flexibility. The hose is constituted by an inner veneer layer of THV, a terpolymer of tetrafluoroethylene, hexafluoropropylene and vinylidene fluoride, as a permeation barrier layer. This inner layer is reinforced by an elastomeric tie layer, a reinforcing layer and an elastomeric cover.
