Abstract: A guide wire includes a wire body having a first wire disposed at a distal end and a second wire joined to a proximal end of the first wire at a joint by welding. The joint is curved. In the joint, at least one component (e.g., Ti) of the material of the first wire decreases toward the proximal end and at least one component (e.g., Fe) of the material of the second wire decreases toward the distal end. When a tensile test is conducted on a region of the wire body including the joint, the region of the wire body has, in a tensile load and elongation diagram, an elastic section extending substantially straight upwardly to the right, a yield section extending substantially horizontally or upwardly to the right from the elastic section, and a substantially straight section extending upwardly to the right from the yield section.

Abstract: A guide wire for a catheter is inserted for use into the catheter and has a wire body, a reshapeable shaping ribbon (wire material) mounted such that a part of the base end side of the shaping ribbon is fixed to the front end side (small diameter section) of the wire body and a part of the front end side of the shaping ribbon extends in the direction to the front end of the guide wire from the front end of the wire body, and a helical coil installed so as to cover both the front end side of the wire body and the shaping ribbon. The coil is divided into a first coil and a second coil, and the first coil is divided into a fine pitch section and a rough pitch section. The bending rigidity of the fine pitch section is greater than that of the rough pitch section.
