A guide wire (1) includes a core (3) possessing a distal end part (31) and a proximal end part (32), a distal covering layer covering the distal end part of the core, and a proximal covering layer (5) covering the proximal end part of the core. The proximal covering layer includes a first layer (6) that covers the surface of the core, and a second layer (7) that partly covers the surface of the first layer. The first layer has a first part (62) which is not covered by the second layer and a second part (61) which is covered by the second layer, and the surface of the second part is tightly surrounded by the proximal end of the distal covering layer (4).
