PROBLEM TO BE SOLVED: To provide a gas conduit, having flexibility such that it can be bent by a human hand when a small obstacle exists, while maintaining performance characteristics required for the gas conduit. SOLUTION: The gas conduit using as a material a thermoplastic elastomer composition, having a structure with dynamically crosslinked elastomer compositions dispersed in a thermoplastic resin composition matrix, has a Young's modulus of 30-400 MPa and a methane gas permeability of 20×10-10 cc.cm/cm2.s.cmHg or less.
