Abstract
A guide wire including a core shaft including a distal end portion having a pseudoelastic property, a tip joined to a distal end of the distal end portion of the core shaft, and an auxiliary wire that is arranged parallel to the distal end portion of the core shaft. The auxiliary wire has a distal end joined to the tip and a rear end joined to the core shaft. The auxiliary wire has a high flexibility, a high breaking strength, and a short breaking elongation compared to the distal end portion of the core shaft.
