<P>PROBLEM TO BE SOLVED: To provide a tubular structure requiring no washing by making the internal wall of the tubular structure completely super-hydrophobic, and a method for easily and efficiently producing the tubular structure. Ž<P>SOLUTION: The tubular structure for transferring an aqueous solution is formed by coating the internal wall surface of a tubular solid base material (X) with a super-hydrophobic coat made of a nano-structure (Y) obtained by bonding a hydrophobic group (C) to silica nano-fiber (B). The method for producing the tubular structure for transferring the aqueous solution includes forming a polymer layer with a polyethylene-imine skeleton on the inner surface of the tubular solid base material (X), bringing the polymer layer into contact with a silica source liquid, and then performing hydrophobic treatment to form the internal wall of the base material (X) into a super-hydrophobic surface.
