Claims (4)

A linear first wire disposed on the distal end side;
A linear second wire that is disposed on the base end side of the first wire and is made of a material having a larger elastic modulus than the constituent material of the first wire;
The first wire and the second wire are connected by welding,
The outer diameters of the first wire and the second wire are from the position on the proximal end side to the position on the proximal end side from the welded portion of the first wire and the second wire to the position on the distal end side from the welded portion. A guide wire that gradually decreases toward the distal end. 2. The guide wire according to claim 1, wherein a connecting end surface of the first wire and the second wire is substantially perpendicular to an axial direction of both wires. 2. The guide wire according to claim 1, wherein a connection end surface between the first wire and the second wire is inclined with respect to a plane perpendicular to the axial direction of the two wires.
