The present invention provides a stent including a main body and a plurality of protruding parts that are configured at two opposite side edges of the main body and arranged in an interlaced manner or a stent including at least one line rib that is bended to form at least two supporting line ribs and at least one bending part is formed at the intersection of the supporting line ribs. A manufacturing method of the stent mainly includes performing a precision stamping process via stamping dies, and utilizing rolling-molding technology to roll a semi-finished product of the stent into a cylindrical shape without being followed by a precision welding procedures. Therefore, the preset invention is capable of improving product yields for mass production, reducing manufacturing time and effectively reducing manufacturing cost, and further reducing the price of the stent to benefit more patients.
