[Problem] There is provided a guide wire which is flexible in a distal portion and which can prevent occurrence of damage such as breakage and separation of a coil in the distal portion.[Means for Resolution] A guide wire 100 has an elongated core member 110 and a tubular body 120 located so as to cover a periphery of a distal portion 111 of the core member. The tubular body is formed using a belt-shaped member 130 wound in a spiral shape, and has an engagement portion 133 which causes side portions 131a and 131b adjacent in a longitudinal axis direction of the core member to engage with each other in the belt-shaped member.
