PROBLEM TO BE SOLVED: To provide a guide wire which facilitates selecting a branch part of an organism lumen.SOLUTION: A guide wire 100 comprises: a long-sized core member 110； and a coil member 120 coiled so as to at least partially cover the tip of the core member. The coil member includes an axis crossing region 121 in which the center axis C1 of the coil member crosses the long axis direction X of the core member, at least at the tip of the core member.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】生体管腔の分岐部の選択をより一層容易に行うことができるガイドワイヤを提供する。【解決手段】ガイドワイヤ１００は、長尺状のコア部材１１０と、コア部材の先端部の少なくとも一部を覆うように巻回されたコイル部材１２０と、を有し、コイル部材は、少なくとも先端部において、コイル部材の中心軸Ｃ１がコア部材の長軸方向Ｘと交差するように巻回された軸交差領域１２１を備える。【選択図】図１
