A synthetic resin tube with gas barrier properties, which is flexible and easily bendable, and moreover, is high in gas barrier properties, is provided. The synthetic resin tube has gas barrier properties to an extent such that a gas is hardly passed. A first layer (17) of polyurethane is provided on an inner circumferential face and a second layer (19) of an ethylene-vinyl alcohol copolymer to be concentrically provided outside of the first layer. A third layer of polyurethane is concentrically provided outside of the second layer (19) as well.
