To provide a refrigerant transporting hose which solves the problems of flexibility and impulse-proof properties in the refrigerant transporting hose using the laminated structure of an acid-modified fluorocarbon resin layer and a polyamide resin layer for an inner surface resin layer and is excellent in gas-barrier properties, flexibility, and durability.

The refrigerant transporting hose has the inner surface resin layer 2 of the three-layer laminated structure in which the acid-modified fluorocarbon resin layer 2A, the polyamide resin layer 2B, and a polyamide/polyolefin elastomer composite resin layer 2 are laminated from its inside. Preferably, the thickness of the acid-modified fluorocarbon resin layer is 100 μm or below, the thickness of the polyamide resin layer is 100 μm or below, and the thickness of the polyamide/polyolefin elastomer composite resin layer is at least 50 μm.
