A medical guide wire () is made in which at least a fluororesin coating layer () is formed on the surface of a metal wire (), wherein particulate matter is present in the fluororesin coating layer (), and the fluororesin coating layer covers the particulate matter and at least some of the particulate matter is formed in surface protrusion-shaped projections (). It is thus possible to provide a medical guide wire that is inexpensive to manufacture and whose strength is unaffected and frictional resistance is low, and manufacturing method for the same.

Medical guide wire and process for production thereof

A method for the manufacture of a medical wire includes manufacturing a fluororesin-coated wire and irradiating with infrared radiation. The fluororesin-coated wire is manufactured with a fluororesin-containing liquid, or fluororesin powder body being applied to the outer circumference of a superelastic alloy wire or of a resin-coated superelastic alloy wire. The fluororesin-coated wire is irradiated with a defined wavelength of infrared radiation for a defined period of time.
