ABSTRACT OF THE DISCLOSURE A guide wire for use with a catheter is provided which comprises an elongated core including a body portion having high rigidity and a distal portion integrally formed with the body portion, but having a smaller diameter and lower rigidity than the body portion, a radiographically sensitive ring at the leading edge of the core, and an envelope of synthetic resin enclosing the entire core including the radiographically sensitive ring and having a substantially even outer diameter. The radiographically sensitive ring at the core leading edge ensures that the leading edge is visually located through an x-ray radiographic observation, facilitating insertion of the guide wire and the catheter into a blood vessel.
