PROBLEM TO BE SOLVED: To provide a sheath for introducer which can prevent curling up of a tip at the time of being introduced to a puncture portion even if the wall thickness is thinned.SOLUTION: A sheath 10 for introducer includes a sheath tube 11 which is formed of a tubular member having a hollow part to which a long body can be inserted, and has a tip 11a whose outer diameter is tapered off and a body part 11b whose outer diameter is constant. The tip 11a of the sheath tube 11 includes a recessed part 11ab which is curved in a recessed manner toward the inner side in a radial direction from an end 11aa for making the long body protrude and a projecting part 11ac which is continuous to the recessed part 11ab and curved in a protruding manner to the outer side in the radial direction on a cross section in parallel with the axial direction. |
