Provided is a medical device that exhibits excellent surface lubricity or antithrombogenicity during use. A medical device comprising a base material layer made of a polymer material and a coating layer covering the surface of the base material layer, wherein the coating layer is made of a hydrophilic polymer, The polymer material forming the layer has, in the molecule, a first higher-order structure and a first functional group provided at at least one end of the first higher-order structure, and the hydrophilic property. A polymer having a second higher order structure capable of interacting with the first higher order structure in the molecule; and the first functional group provided at at least one end of the second higher order structure; And a second functional group capable of hydrogen bonding.
