Zusammenfassung:	Provided are a drug-eluting medical device in which drug elution is sustained release and the peeling durability of the coating layer is high, and a method for producing the same. A drug-eluting medical device including: a substrate 20; a first coating layer 31 having a first polymer obtained by autoxidation polymerization of a dopamine molecule or an analog thereof on the substrate 20; a second coating layer 32 having a second polymer covalently bonded to the first polymer on the first coating layer 31; and a third coating layer 33 having a drug and a third polymer supporting the drug on the second coating layer 32, wherein the second polymer and the third polymer form an interpenetrating polymer network structure.
