HIGH PERFORMANCE BIOABSORBABLE STENT

To provide a stent excellent in deformability, capable of maintaining a radial force for a longer period of time, and having bioabsorbability and a method of producing the same. The bioabsorbable stent has a core structure including a magnesium alloy and a corrosion resistant layer on the core structure, wherein the core structure is formed from a magnesium alloy containing 90 mass% or more of Mg as a main component, Zn, Zr, and Mn as accessory components, and 30 ppm or less of unavoidable impurities selected from the group consisting of Fe, Ni, Co, and Cu, and the alloy excluding aluminum and at least one sort of rare earths selected from the group consisting of Sc, Y, Dy, Sm, Ce, Gd, and La; and the corrosion resistant layer containing magnesium fluoride as a main component with a hydrophilic smooth surface is formed on the core structure with a smooth surface.
