A medical elongated body that is capable of improving convenience during use by a surgeon, and capable of preventing peeling, from a catheter main body, of a drug portion (a hydrophilic coating) containing metal ions and a drug when disposed on a wound site of a patient. An introducer sheath includes a tubular sheath configured to be percutaneously inserted into a blood vessel, and a hub connected to a proximal portion of the tubular sheath, in which the tubular sheath includes a first region and a second region located on a proximal side relative to the first region, the first region has a first hydrophilic coating having lubricity, the second region includes a groove portion extending from a distal side of the tubular sheath toward a proximal side of the tubular sheath, the groove portion having a second hydrophilic coating containing at least one of metal ions and a drug. |
