Abstract
A drug coating layer which is a drug coating layer having a morphological form including a plurality of elongated bodies having long axes that each crystal of a water-insoluble drug independently has on a substrate surface, in which the long axes of the elongated bodies are nearly linear in shape, and the long axes of the elongated bodies form an angle in a predetermined range with respect to a substrate plane with which the long axis of the elongated body intersects. The drug coating layer can provide low toxicity and a high intravascular stenosis inhibitory effect.
