PROBLEM TO BE SOLVED: To enhance the sticking property (airtightness) and hemostatic performance of a hemostatic valve by reducing resistance to catheter insertion. SOLUTION: A hemostatic valve 1 clamped in an introducer used for introducing a catheter or the like into a blood vessel comprises a thick-walled unclamping part 3 and a thin-walled clamping part 2; a slit 4 extending outwards in plural lines from the center of the unclamping part 3 and leading from the top to bottom surfaces thereof is formed in the unclamping part 3, and a plurality of half-slits 5 or grooves leading from the bottom or top surface of the unclamping part 3 to a mid-part are formed on the outer periphery of the slit 4. |
