A fuel cell hose which is superior in flexibility (low-temperature flexing property) and in barrier properties against hydrogen gas or water, and causes no defects such as buckling or cracking when press-fitting of a connector. The hose comprises an inner layer1in contact with fluid and an outer layer3formed on an outer peripheral surface of the inner layer, the inner layer being formed by a material (A) comprising a polyolefin resin and a styrene-isobutylene block copolymer and the outer layer being formed by a material (B) comprising a polyamide resin and a styrene-isobutylene block copolymer.
