Zusammenfassung:	To provide: a composition for a refrigerant transport hose capable of achieving both flexibility and resistance to water vapor permeability; and a refrigerant transport hose.SOLUTION: A resin composition for a refrigerant transport hose in the present disclosure includes a polyolefin-based resin, an elastomer having an isobutylene skeleton, and an olefin-based block copolymer. The resin composition for the refrigerant transport hose preferably uses the polyolefin-based resin as a matrix, and preferably has a sea-island structure using the elastomer having the isobutylene skeleton as a domain. A refrigerant transport hose in the present disclosure includes a layer containing the resin composition for the refrigerant transport hose.SELECTED DRAWING: Figure 1 【課題】本開示は、柔軟性及び耐水蒸気透過性を両立させることができる、冷媒輸送ホース用組成物及び冷媒輸送ホースを提供する。【解決手段】本開示の冷媒輸送ホース用樹脂組成物は、ポリオレフィン系樹脂、イソブチレン骨格を有するエラストマー、及びオレフィン系ブロック共重合体を含有している。本開示の冷媒輸送ホース用樹脂組成物は、前記ポリオレフィン系樹脂をマトリクスとし、かつ前記イソブチレン骨格を有するエラストマーをドメインとする海島構造を有していることが好ましい。本開示の冷媒輸送ホースは、本開示の冷媒輸送ホース用樹脂組成物を含有している層を有している。【選択図】図１
