A biodegradable polymer-coated stent is provided that is effective in delaying loss of physical properties of the core structure, particularly radial force. A core structure made of a bioabsorbable material (magnesium or the like), a first coating layer made of a biodegradable first polymer covering the entire surface of the core structure, and an entire surface or part of the first coating layer. It is comprised from the 2nd coating layer which consists of a biodegradable 2nd polymer to coat | cover, The glass transition point of the said 1st polymer is less than 37 degreeC, The glass transition point of the said 2nd polymer is 47 degreeC or more A stent characterized by |
