A stent, composed of linear components, comes into close contact with a tissue in vivo upon being deformed when set indwelling in vivo. The stent has linear components which are deformed to exhibit a force for maintaining dilation when the stent is set indwelling in vivo. The linear components deformed when the stent is set indwelling in vivo are composed of non-biodegradable metallic linear components and a plurality of biodegradable material-made linear components which are bonded to the non-biodegradable metallic linear components. Furthermore, when set indwelling in vivo, the stent exhibits the force for maintaining the dilation owing to both the non-biodegradable metallic linear components and the biodegradable material-made linear components. After a predetermined period of time, biodegradation of the biodegradable material-made linear components proceeds, which results in a lowering of the force for maintaining the dilation |
