PROBLEM TO BE SOLVED: To provide a tubular body composed of a styrenic thermoplastic elastomer composition having excellent flexibility, moldability, oil resistance, heat resistance, and kinking resistance. SOLUTION: The tubular body is composed of the styrenic thermoplastic elastomer composition which comprises a specific block copolymer (a), a hydrocarbon rubber softening agent (b), and an olefinic resin (c) at a compounding ratio (a)/(b) (by weight) of component (a) to component (b) of 20/80 to 80/20 and, simultaneously, at a ratio of component (c) to 100 pts.wt. sum of components (A) and (B) of 1 to 300 pts.wt. and is dynamically heat treated in the presence of a crosslinking agent.
