To provide a hose capable of exhibiting heat resistance and oil resistance at a high temperature over 150°C.
The hose is formed out of a thermoplastic elastomer composition obtained by dynamically crosslinking a raw material composition containing the following components (A), (B), (C) and (D), and 0.05-5 pts.mass crosslinking agent based on 100 pts.mass component (A): component (A): 50-85 pts.mass acryl rubber based on 100 pts.mass total of the components (A) and (B); component (B): 15-50 pts.mass thermoplastic polyester resin based on 100 pts.mass total of the components (A) and (B); component (C): 1-35 pts.mass graft copolymer comprising an olefinic polymer segment and a vinylic copolymer segment, or precursor thereof based on 100 pts.mass total of the components (A) and (B); and component (D): ≤60 pts.mass plasticizer based on 100 pts.mass component (A).
