Abstract: The present invention provides a stent that can obtain sufficient strength while an inner side of the stent is easily endothelialized and moreover, can prevent occlusion of a branch blood vessel. Specifically, a stent body capable of diameter expansion is provided. A tubular film 3 is held by the stent body. In the tubular film 3, a plurality of communication holes 4 communicating between an inside and an outside are formed. Band-shaped portions 7 and 8 are formed between the communication holes 4 adjacent to each other. A wide-width portion and a narrow portion are not generated in the band-shaped portions 7 and 8. Strength of a part of the band-shaped portions 7 and 8 is not lowered. Generation of the wide-width portion in the band-shaped portions 7 and 8 is prevented.
