主权项 1. A tube for transporting a fluid, comprising a composition comprising (A) a thermoplastic elastomer, (B) 1 to 50 parts by mass of flat-shaped graphite based on 100 parts by mass of the thermoplastic elastomer, and (C) 0.1 to 50 parts by mass of a polyolefin resin based on 100 parts by mass of the thermoplastic elastomer, wherein the flat-shaped graphite has an average particle diameter of 1 to 100 μm, and an aspect ratio thereof is 1≦aspect ratio≦5, wherein the thermoplastic elastomer of the component (A) is a polystyrene base thermoplastic elastomer in which a principal chain of a soft segment comprises a saturated bond, wherein the polystyrene base thermoplastic elastomer of the component (A) is at least one selected from the group consisting of a styrene-isobutylene-styrene block copolymer (SIBS), a styrene-ethylene/butylene-styrene block copolymer (SEBS) and a styrene-ethylene/propylene-styrene block copolymer (SEPS), and wherein a sheet of said composition having a thickness of 0.5 mm has an air permeability of 120×10−5 cm3/m2·24 hr·Pa or less.
