Abstract
A guide wire includes a wire body and a coil provided so as to cover the distal side of the wire body. The wire body has a first wire disposed on the distal side, a second wire disposed on the proximal side from the first wire, and a third wire disposed on the proximal side from the second wire. The first wire is made from a reshapable metal material such as a stainless steel. The second wire is made from a pseudo-elastic alloy such as a Ni-Ti alloy. The third wire is made from a material having an elastic modulus larger than that of a material for forming the second wire. The first wire and the second wire are joined to each other by welding, and similarly the second wire and the third wire are joined to each other by welding.
