Zusammenfassung:PURPOSE: A guide wire is provided to supply excellent flexibility and operability by welding a first wire and a second wire with different physical properties and to increase the bond strength between the first wire and the second wire. CONSTITUTION: A guide wire(1) comprises a wire body(10) consisting of a linear first wire(2) and a second wire(3). The first wire is installed with a coil(4) having X-ray contrast on the circumference of the front end part. The firs wire and the second wire are welded and form a junction(14). The junction is a curved shape. In the junction, a first component(example: Ti) among configuration materials of the first wire is reducing toward the rear end part, and a second component(example: Fe) among configuration materials of the second wire is reducing toward the front end part.
