The present invention provides a medical instrument having a lubricating layer that reduces the association of polymer brushes while ensuring hemocompatibility. This medical instrument has a base material layer and a lubricating layer comprising polymer chains that have a length of less than 10 μm present in the form of brushes on the base material layer, the polymer chains being formed from a hemocompatible copolymer of zwitterionic monomers and anionic monomers, and carrying a negative charge during contact with body fluids. |
