To provide a vinyl chloride resin tube for lining a protective tube having both superior mechanical strength and impact resistance and excellent also in suitability to application.

The vinyl chloride resin tube comprises a vinyl chloride resin composition prepared by adding 3-30 pts.wt. thermoplastic elastomer (F) to 100 pts.wt. composite vinyl chloride resin (E) obtained by copolymerizing 100 pts.wt. acrylic monomer components (A) including ≥50 wt.% alkyl(meth)acrylate monomer and <50 wt.% another acrylic monomer with a polyfunctional monomer component (B) and graft-copolymerizing 3-10 wt.% of the resulting acrylic copolymer (C) with 97-90 wt.% vinyl chloride monomer or vinyl chloride monomer and another copolymerizable monomer (D). The vinyl chloride resin tube sticks fast to the internal surface of an existing tube when inserted into the existing tube and heated.
