An object of the present invention is to provide a guidewire preventing cracks from being generated at a hydrophilic coating agent and excellent in lubricity by securing flexibility of the hydrophilic coating agent on its surface side even in a case of using the cross-linked hydrophilic coating agent. The guidewire includes a core shaft, a coiled body provided at a tip portion of the core shaft, a most distal portion fixing a front end of the core shaft and a front end of the coiled body, and a hydrophilic coating agent coating the coiled body and the most distal portion and cross-linked by a cross-linking agent. The degree of cross-linking of the hydrophilic coating agent decreases from a side of the coiled body toward a surface side.
