<p>[Problem] To provide an introducer sheath that is capable of preventing a tip section from curling when introduced to a puncture site, even if the wall thickness is made thin. [Solution] An introducer sheath (10) is formed from a tubular member provided with a hollow section through which an elongated body can be inserted, and is provided with a sheath tube (11) that is provided with a tip section (11a) having a tapered outer diameter, and a body section (11b) having a fixed outer diameter. The tip section (11a) of the sheath tube (11) is provided with, in a cross section parallel to the axial direction: a concave section (11ab) that is curved in a concave shape in a radially inward direction from an end (11aa), through which an elongated body is allowed to protrude; and a convex section (11ac) that is connected to the concave section (11ab), and is curved in a convex shape in a radially outward direction.</p> |
