A guidewire includes a core wire, a coil body that covers the core wire, a tip portion that fixes a distal end of the core wire to a distal end of the coil body, and a resin layer formed on an outer peripheral surface of the core wire. A gap is provided between an outer peripheral surface of the resin layer and an inner peripheral surface of the coil body, so that the resin layer and the coil body are not in contact with each other.
