Abstract
Provided are a stent to be placed in the bile duct and a process for producing the stent, the stent hollow being less apt to be blocked even when the stent is placed in the bile duct for a long period. The inner peripheral surface of the stent is coated with a resin layer with resistance to sludge formation that includes a polymer obtained by polymerizing 2-methoxyethyl acrylate. This stent is produced by applying a coating fluid that contains 0.1-0.5 mass % polymer obtained by polymerizing 2-methoxyethyl acrylate, to the inner peripheral surface of a stent.
