A guide wire includes a core possessing a distal end part and a proximal end part, a distal covering layer covering the distal end part of the core, and a proximal covering layer covering the proximal end part of the core. The proximal covering layer includes a first layer that covers the surface of the core, and a second layer that partly covers the surface of the first layer. The first layer has a first part which is not covered by the second layer and a second part 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.
