A guide wire is disclosed, the guide wire including a flexible wire main body, a coil that is intermediately disposed in a longitudinal direction of the wire main body in an outer periphery of the wire main body, and a support portion that supports at least one of a distal end and a proximal end of the coil so as to be rotatable around a central axis O of the wire main body. In a natural state where an external force is not supplied to the guide wire, the support portion supports in a state where an inner peripheral portion of the coil and an outer peripheral portion of the wire main body are separated from each other.
