Title: Medical guidewire

Abstract: The present invention provides a guidewire having a reduced diameter, which ensures rigidity and excellent guidance ability in spite of its reduced diameter, and which achieves an excellent sliding ability and insertion/pulling-out ability with respect to a catheter or the like. The guidewire has an inner core formed of a single wire having an uneven surface on its outer circumferential surface, a high-polymer coating which densely covers the outer circumferential surface of the inner core, and an uneven surface formed on the outer circumferential surface of the high-polymer coating by an influence from the uneven surface on the outer circumferential surface of the inner core.
