PROBLEM TO BE SOLVED: To provide a medical guidewire which achieves reduced sliding resistance when pulled inside a catheter, inside a tubular organ or inside intracorporeal tissue, and has excellent manipulability for a physician who performs an operation.SOLUTION: Since an area between a proximal end portion of a coiled body 5 and a core shaft 3 is formed into a streamlined shape, it is possible to reduce the sliding resistance in the case of pulling the medical guidewire inside the catheter, inside the tubular organ or inside the intracorporeal tissue, and it is possible to provide the medical guidewire with excellent manipulability for the physician who performs the operation. It is desirable to form the streamlined shape by a brazing material that joins the proximal end portion of the coiled body 5 and the core shaft 3.COPYRIGHT: (C)2011,JPO&INPIT【課題】医療用ガイドワイヤをカテーテル内、管状器官内または体内組織内で引く場合における摺動抵抗を低減することができ、手技を行う医者にとって操作性の良い医療用ガイドワイヤを提供する。【解決手段】コイル体5の基端部とコアシャフト3との間を流線形状に形成したので、医療用ガイドワイヤ1をカテーテル内、管状器官内または体内組織内で引く場合における摺動抵抗を低減することができ、手技を行う医者にとって操作性の良い医療用ガイドワイヤを提供することができる。なお、流線形状を、コイル体5の基端部とコアシャフト3との間を接合するロウ材で形成するのが望ましい。【選択図】図4
