PROBLEM TO BE SOLVED: To provide a guide wire for preventing an excessive jumping while securing a shape-keeping property of a distal end portion, so as to ensure selectivity.SOLUTION: The guide wire 1A has a core shaft 2, and a coil body 3 covering at least a distal end portion of the core shaft. The distal end portion of the core shaft 2 has a curvature X1 with respect to a proximal end of the core shaft 2 along the center line L1 of the core shaft 2 in the long-axis direction. Also, at least a distal end portion of the coil body 3 has a curvature X2 with respect to a proximal end of the coil body 3 along the center line of the coil body 3 in the long-axis direction. When the core shaft 2 and the coil body 3 are assembled to each other, the distal end portion k of the guide wire 1A has a curvature X3 with respect to a proximal end of the guide wire 1A along the longitudinal center line of the guide wire 1A, and the curvatures X1 to X3 have the following relation: X1
