A medical device includes a base layer, and a lubrication layer supported on at least a part of the base layer, wherein the lubrication layer contains a block copolymer (A) composed of a first constituting unit derived from a reactive monomer that has an epoxy group and a second constituting unit derived from at least one hydrophilic monomer selected from the group consisting of acrylamide and an acrylamide derivative, and a polymer (B) composed of a constituting unit derived from at least one hydrophilic monomer selected from the group consisting of acrylamide and an acrylamide derivative, wherein the block copolymer (A) is contained in a proportion of 20 to 80% by weight relative to the total weight of the block copolymer (A) and the polymer (B), and wherein the block copolymer (A) is crosslinked or polymerized to form a mesh structure.
