A medical device wherein a metal base and a surface lubricating layer are fixed with each other more firmly. The medical device permanently exhibits excellent surface lubricity when in use. A medical device which has a lubricating surface when wet, is characterized by comprising a base layer which is composed of a metal material, an intermediate layer which covers at least a part of the base layer and is composed of a compound that has a plurality of thiol groups in each molecule, and a surface lubricating layer which covers the surface of the intermediate layer and is composed of a hydrophilic polymer that has a reactive functional group. The medical device is also characterized in that the surface lubricating layer is bonded to the base layer via the intermediate layer by reacting the compound having thiol groups with the hydrophilic polymer.
