An stent includes an outer stent base layer formed from a metallic material, an inner stent base layer formed from a metallic material and positioned inside the outer stent base layer, and a resinous adhesive layer containing a biodegradable polymer which is placed between the outer stent base layer and the inner stent base layer, and bonds together the outer stent base layer and the inner stent base layer. The resinous adhesive layer contains a biodegradable polymer containing a physiologically active substance in such a manner as to permit it to release itself. |
