A medical device wherein a surface lubricating layer and one of various polymer bases are fixed with each other firmly by a relatively simple technique. The medical device permanently exhibits excellent surface lubricity when in use. The medical device has a lubricating surface when wet, and includes a base layer at least the surface of which is composed of a polymer material, a compound (thiol compound) which is supported on at least a part of the base layer and has a plurality of thiol groups in each molecule, and a surface lubricating layer which covers the thiol compound and is composed of a hydrophilic polymer that has a reactive functional group.
