1. A guide wire comprising:
- a wire body;
a first coil having a helical shape, and being disposed on a distal end side of said wire body;
a second coil having a helical shape, and being disposed on a distal end side of said first coil; and
an elongate member having a section that extends in a longitudinal direction of said wire body, and made of a reshapeable material, said material being the same as a material of one of said first coil and said second coil,wherein at least a portion of said section is located inside said second coil, and said elongate member and said one of said first coil or said second coil are a single unitary part,wherein a distal end of said wire body is inserted into an inside of said first and second coils substantially at an internal center thereof, andwherein a distal end of said elongate member is fixed on said second coil.

Abstract
A guide wire includes a wire body, a first coil, a second coil, and an elongate member. The first coil has a helical shape, and is disposed on a distal end side of the guide wire. The second coil has a helical shape, and is disposed on a distal end side of the first coil. The elongate member has a section that extends a longitudinal direction of the wire body. At least a portion of the section is located inside the second coil, and the elongate member is formed integrally with the first coil or the second coil.
