A guide wire 1 according to the present invention includes a flexible wire main body 11, a coil 5 that is intermediately disposed in a longitudinal direction of the wire main body 11 in an outer periphery of the wire main body 11, and a support portion 7 that supports at least one of a distal end and a proximal end of the coil 5 so as to be rotatable around a central axis O of the wire main body 11. In addition, in a natural state where an external force is not supplied to the guide wire 1, the support portion 7 supports in a state where an inner peripheral portion 51 of the coil 5 and an outer peripheral portion 111 of the wire main body 11 are separated from each other.
