A guidewire having high rotational torque transmissibility and high pushing torque transmissibility and having favorable restorability is provided. The guidewire has an outer coil having a tapered coil portion constituted by at least one strand wound to decrease an outer diameter toward a front end of a core shaft and an inner coil arranged inside the outer coil. An outer diameter on a front side of the inner coil arranged on a front side of the tapered coil portion is smaller than an outer diameter on a rear side of the inner coil.
