A tube having high fuel permeation resistance and high flexibility is provided. The tube includes a barrier layer including metaxylylene group-containing polyamide resin and flexible resin which exhibits compatibility with metaxylylene group-containing polyamide resin and is softer than metaxylylene group-containing polyamide resin, and a polyamide resin layer. The flexible resin falls in a range from 10% to 30% by weight of the total amount of the barrier layer and has a flexural modulus of lower than or equal to 2000 MPa, as measured according to
