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.

Guide wire

A guide wire includes a first wire disposed on the distal side and composed of a first material, and a second wire disposed on the proximal side of the first wire and composed of a second material. The first and second wires are connected to each other through an intermediate member which includes a core portion and an outer layer covering the outer periphery of the core portion. The core portion is wholly or partly composed of a material different from the material of the outer layer, and at least one of the core portion and the outer layer is composed of the first material or the second material. The proximal portion of the first wire and the distal portion of the intermediate member are joined to each other, and the distal portion of the second wire and the proximal portion of the intermediate member are joined to each other.
