Guide wires

Abstract

A guide wire in which a distal end portion of the guide wire can be easily bent in a specific plane direction in shaping, is provided. A guide wire includes a core shaft having a maximum diameter in a cross section orthogonal to an axial direction of the core shaft and an orthogonal diameter in a direction orthogonal to a direction of the maximum diameter, the core shaft includes a first specific portion located on a distal end side of the core shaft and having an oblateness between 7% and 35%, where oblateness is defined as the difference between the maximum diameter and the orthogonal diameter divided by the maximum diameter. The first specific portion of the core shaft can be 5 mm or more in the axial direction.
