A guide wire includes an elongated wire body and a radiopaque part capable of forming an X-ray image and located at the distal end portion of the wire body. The radiopaque part has a radiopaque member and a resin coating layer. The radiopaque member is composed of a metallic material capable of forming an X-ray image and arranged outside the wire body and in the lengthwise direction of the wire body. The resin coating layer covers the radiopaque member and at least part of coating layer contains a radiopaque material capable of forming an X-ray image. The radiopaque part is divided into a first radiopaque region, a second radiopaque region, and a third radiopaque region which are sequentially arranged from the distal end in the lengthwise direction of the wire body.
