Zusammenfassung:	To provide a refrigerant transport hose excellent in both durability and barrier property, which has proper bending strength.SOLUTION: Provided is a multilayer refrigerant transport hose 10 for transporting fluid including a refrigerant and oil, including, as a layer that comes in direct contact with the refrigerant and the oil, an inner resin layer which includes at least a block copolymer (A) having a structure in which a polyamide block is grafted to a polyolefin skeleton, and an outer resin layer arranged outside the inner resin layer, which includes at least a polyamide resin (B).SELECTED DRAWING: Figure 1 【課題】耐久性及びバリア性の双方に優れ、適切な曲げ強度を有する冷媒輸送ホースを提供すること。【解決手段】冷媒及びオイルを含む流体を輸送するための多層構造の冷媒輸送ホースであって、前記冷媒及び前記オイルと直接接する層として、ポリオレフィン骨格にポリアミドブロックがグラフトされた構造を有するブロック共重合体（Ａ）を少なくとも含む内側樹脂層と、前記内側樹脂層よりも外側に配置された、ポリアミド樹脂（Ｂ）を少なくとも含む外側樹脂層と、を有することを特徴とする、冷媒輸送ホース１０。【選択図】図１
