Abstract
A guide wire includes a first wire located at the distal end of the guide wire, a second wire located at the proximal end of the guide wire and having a flexural rigidity greater than that of the first wire, and a tubular connector for joining the first and second wires. The connector has one or more grooves or slits formed on the distal side of the boundary between the first wire and the second wire. The connector is formed of a material different from the material of the first wire. The proximal portion of the first wire is provided with a thin metal coating. The first wire is joined to the connector by brazing at the portion provided with the thin metal coating.
