A stent which can suppress galvanic corrosion while radiopacity is sufficiently ensured. The stent includes a sintered body of a base material that is formed of a first metal material with a second metal material that is dispersed in the base material. The second metal material has a specific gravity higher than that of the first metal material, and has a corrosion potential expressed by a corrosion potential of the first metal material ±200 mV.
