Zusammenfassung:	To provide a guide wire capable of relaxing a rigidity gap on a core shaft, and capable of improving bond strength of first and second shafts.SOLUTION: A guide wire has a core shaft, the core shaft comprises: a first shaft provided at a tip side of the core shaft; and a second shaft which has a tip end part to which a base end part of the first shaft is joined, and is formed of a material different from a material of the first shaft. On an outer peripheral surface of the tip end part of the second shaft, a groove is formed, the groove extending from the tip end of the second shaft to the base end side of the second shaft. The base end part of the first shaft is inserted into the groove on the second shaft.SELECTED DRAWING: Figure 1 【課題】コアシャフトにおける剛性ギャップを緩和し、第１のシャフトと第２のシャフトとの接合強度の向上を図る。【解決手段】ガイドワイヤは、コアシャフトを備え、コアシャフトは、コアシャフトの先端側に位置する第１のシャフトと、第１のシャフトの基端部が接合される先端部を有し、かつ、第１のシャフトとは材質の異なる第２のシャフトと、を有する。第２のシャフトの先端部の外周面には、第２のシャフトの先端から第２のシャフトの基端側に向かって延びている溝が形成されている。第１のシャフトの基端部は、第２のシャフトの溝内に挿入されている。【選択図】図１
